Vim using <c-6> to switch alternative file is not functional on Mac terminal while MacVim works.
The current version of Vim is 7.3.
To switch to the alternate file you can use control-shift-6 (<C-^>) or :e #. Both of these work in the Terminal.
Take a look at :h CTRL-^
It's not possible to map <C-#> in terminal mode. It's a limitation of terminals that they can't handle most Ctrl key combinations. The only ones that work are A-Z and just a couple others. Similarly, you can't detect combinations like Ctrl+Shift+a; they just come through as <C-a>.
You'll either have to remap the key to something else, or configure your terminal emulator to send a different key combination when you press that. Either way, you'd have to configure your Vim to accept something other than <C-6> when using a terminal.
I'm running Vim on a gnome terminal. But the alt key mappings are not working. For example:
:imap <A-i> <Esc>
It works fine in GVim. But when I run the same command with Vim in the gnome terminal it does nothing.
I'm using Windows 7, The problem is with the terminal, right?
The problem
There are two ways for a terminal emulator to send an Alt key (usually called a Meta key as actual terminals didn't have Alt). It can either send 8 bit characters and set the high bit when Alt is used, or it can use escape sequences, sending Alt-a as <Esc>a. Vim expects to see the 8 bit encoding rather than the escape sequence.
Some terminal emulators such as xterm can be set to use either mode, but Gnome terminal doesn't offer any such setting. To be honest in these days of Unicode editing, the 8-bit encoding is not such a good idea anyway. But escape sequences are not problem free either; they offer no way of distinguishing between <Esc>j meaning Alt-j vs pressing Esc followed by j.
In earlier terminal use, typing Escj was another way to send a Meta on a keyboard without a Meta key, but this doesn't fit well with vi's use of Esc to leave insert mode.
The solution
It is possible to work around this by configuring vim to map the escape sequences to their Alt combinations.
Add this to your .vimrc:
let c='a'
while c <= 'z'
exec "set <A-".c.">=\e".c
exec "imap \e".c." <A-".c.">"
let c = nr2char(1+char2nr(c))
endw
set timeout ttimeoutlen=50
Alt-letter will now be recognised by vi in a terminal as well as by gvim. The timeout settings are used to work around the ambiguity with escape sequences. Esc and j sent within 50ms will be mapped to <A-j>, greater than 50ms will count as separate keys. That should be enough time to distinguish between Meta encoding and hitting two keys.
If you don't like having timout set, which times out for other mapped key sequences (after a second by default), then you can use ttimeout instead. ttimeout applies only to key codes and not other mappings.
set ttimeout ttimeoutlen=50
For Gnome-terminal, use the following instead:
imap ^[i <Esc>
^[i should be typed by pressing Ctrl-v Alt-i
Attention: You need to yank and put in Vim when you want to copy it elsewhere. If you just copy the mapping in an editor like gedit, the mapping will probably be broken.
EDIT here is an example which makes Alt-k add an empty line above the cursor, and Alt-j add an empty line after the current line.
" Alt-j/k to add a blank line
if has('gui_running')
" the following two lines do not work in vim, but work in Gvim
nnoremap <silent><A-j> :set paste<CR>m`o<Esc>``:set nopaste<CR>
nnoremap <silent><A-k> :set paste<CR>m`O<Esc>``:set nopaste<CR>
else
" these two work in vim
" shrtcut with alt key: press Ctrl-v then Alt-k
" ATTENTION: the following two lines should not be
" edited under other editors like gedit. ^[k and ^[j will be broken!
nnoremap ^[k :set paste<CR>m`O<Esc>``:set nopaste<CR>
nnoremap ^[j :set paste<CR>m`o<Esc>``:set nopaste<CR>
endif
Try
<m-i>
Or, if typing alti inserts a character (like in my case, it inserts a carret: ˆ) just map to that character:
:inoremap ˆ <esc>
Be careful, because this one wouldn't work (at least in my system, MacOS 10.6). The caret waits for a letter, because it's not exactly a caret, it is a circumflex.
It may be that the shortcuts are actually from the Gnome Desktop. Try looking at the Gnome Keyboard Shortcuts tool (System menu, Preferences, Keyboard Shortcuts), which lets you view and modify the shortcuts defined on Gnome Desktop. If the key combination is assigned to a function on Gnome Desktop, then remove it and then that key combo should filter down to Vim properly.
Or you may be right that it is a problem of the terminal. Not all terminals support all key combos. Your problem may be the one described in the Vim help docs at :h map-alt-keys. The docs provide a workaround, but not a very good one.
The same thing happens to me. I searched on Google with "gnome terminal alt key", and found that someone asked almost the same question: "How to disable the alt-hotkey behavior on gnome terminal?" in the first link found. (The second link is just this question)
So, maybe you can try that:
Edit > Keyboard Shortcuts, and uncheck "Enable menu access keys"
Take a look at section 1.10 of http://vimdoc.sourceforge.net/htmldoc/map.html. It seems to indicate that gnome-terminal automatically escapes the Alt modifier, so that it doesn't switch the byte sent in the way that Vim is expecting. The document seems to indicate that there isn't really a way around this except for using a different terminal (such as xterm).
This is certainly frustrating because so far as I can tell Linux machines are also incapable of using the D (Mac's Command or Linux's Super) bindings, so at least as far as the terminal goes, we are limited to Shift and Ctrl modifiers, which is frustrating if we want to ensure that we can use all the commands we use in Gvim on terminal Vim (at least without switching terminals, towards which I'm perhaps overly stubborn - gnome-terminal is just so much prettier). I've been looking for a way around this but have been unable to find anything.

I can open a shell by using the :shell command in Vim, however I can't edit a file and at the same time use the shell.
Is there any way to split Vim in many Windows (or tabs), and have a shell opened in one of them?
Neovim and Vim 8.2 support this natively via the :ter[minal] command.
See terminal-window in the docs for details.
Well it depends on your OS - actually I did not test it on MS Windows - but Conque is one of the best plugins out there.
Actually, it can be better, but works.
:vsp or :sp - splits vim into two instance but you cannot use :shell in only one of them.
Why not display another tab of the terminal not another tab of vim. If you like the idea you can try it: Ctrl-shift-t. and move between them with Ctrl - pageup and Ctrl - pagedown
If you want just a few shell commands you can make any shell command in vim using !
For example :!./a.out.
You can use tmux or screen (second is able to do only horizontal splits without a patch) to split your terminal. But I do not know the way to have one instance of Vim in both panes.
If you haven't found out yet, you can use the amazing screen plugin.
Conque is also exceptional but I find screen much more practical (it wont "litter" your buffer for example and you can just send the commands that you really want after editing them in your buffer)
I guess this is a fairly old question, but now in 2017. We have neovim, which is a fork of vim which adds terminal support.
So invoking :term would open a terminal window. The beauty of this solution as opposed to using tmux (a terminal multiplexer) is that you'll have the same window bindings as your vim setup. neovim is compatible with vim, so you can basically copy and paste your .vimrc and it will just work.
More advantages are you can switch to normal mode on the opened terminal and you can do basic copy and editing. It is also pretty useful for git commits too I guess, since everything in your buffer you can use in auto-complete.
I'll update this answer since vim is also planning to release terminal support, probably in vim 8.1. You can follow the progress here:
https://groups.google.com/forum/#!topic/vim_dev/Q9gUWGCeTXM
Once it's released, I do believe this is a more superior setup than using tmux.
Shougo's VimShell, which can auto-complete file names if used with neocomplcache
Not absolutely what you are asking for, but you may be interested by my plugin vim-notebook which allows the user to keep a background process alive and to make it evaluate part of the current document (and to write the output in the document). It is intended to be used on notebook-style documents containing pieces of code to be evaluated.
With Vim 8.0 or later you can run a terminal emulator in a vim window by using the terminal feature. BTW if you want to simulate modern IDE terminal (like VSCode integrated terminal) in gVim or MacVim, you can put the following configuration in you vimrc.
set shell=/path/to/shell
" Make sure to replace `sh.exe` in BufNr("sh.exe") with your shell executable.
nnoremap <expr> <space> BufNr("sh.exe") > 0 ? (&buftype == 'terminal' ? '<c-^>' : ':b '. BufNr("sh.exe") . '<cr>') : ':terminal ++curwin<cr>'
function! BufNr(pattern)
let bufcount = bufnr("$")
let currbufnr = 1
let nummatches = 0
let firstmatchingbufnr = 0
while currbufnr <= bufcount
if(bufexists(currbufnr))
let currbufname = bufname(currbufnr)
if(match(currbufname, a:pattern) > -1)
let nummatches += 1
let firstmatchingbufnr = currbufnr
endif
endif
let currbufnr = currbufnr + 1
endwhile
return firstmatchingbufnr
endf
Now you can use space in normal mode (or whatever mapping you chosen) to:
Open a terminal in current window if terminal doesn't exists yet.
Switch to terminal buffer if current buffer is not a terminal type.
Switch to previous buffer if current buffer is a terminal buffer.
You may want to open a "screen" program,
split screen, open shell on one and vim on another.
Works for me.
I am currently using tmux.
Installation: sudo apt-get install tmux
Run it: tmux
Ctrl + b followed by Ctr + % : it splits your terminal window in two vertical halves.
Ctrl + "arrow left | arrow right" : moves between terminals.
I am used to Emacs, but I am trying out Vim to see which one I like better.
One thing that I like about Emacs is the ability to run a terminal inside Emacs. Is this possible inside of Vim? I know that you can execute commands from Vim, but I would like to be able to run a terminal inside of a tab.
Outdated from August 2011
Check out Conque Shell (also on GitHub). Lets you run any interactive program inside vim, not just a shell.
I'm not sure exactly what you're trying to achieve (I've never used Emacs), but you can run commands in Vim by typing:
:! somecommand [ENTER]
And if you want to type in several commands, or play around in a shell for a while, you can always use:
:! bash (or your favourite shell) [ENTER]
Once the command or shell terminates, you'll be given the option to press Enter to return to your editor window
Vim is intentionally lightweight and lacking in the ability to do non-editorish type things, just as running a full-blown shell inside a Vim pane/tab, but as mentioned above there are third-party addons such as vim-shell that allow you to do that sort of thing.
Typically if I want to switch between Vim and my shell (Bash), I just hit CTRL+Z to pause the Vim process, play around in my shell, then type 'fg' when I want to go back to Vim - keeping my editor and my shell nice and separate.
Updated answer (11 years later...):
I would recommend using tmux instead of screen as suggested in the original answer below, if you choose to use that solution.
Vim 8.1 now has a built in terminal that can be opened with the :term command. This provides much more complete integration with the rest of the Vim features.
I would definitely recommend screen for something like this. Vim is a text editor, not a shell.
I would use Ctrl+AS to split the current window horizontally, or in Ubuntu's screen and other patched versions, you can use Ctrl+A|(pipe) to split vertically. Then use Ctrl+ATab (or equivalently on some systems, Ctrl+ACtrl+I which may be easier to type) to switch between the windows. There are other commands to change the size and arrangement of the windows.
Or a less advanced use of screen is just to open multiple full-screen windows and toggle between them. This is what I normally do, I only use the split screen feature occasionally.
The GNU Screen Survival Guide question has a number of good tips if you're unfamiliar with its use.
The way that I get around this is:
pause Vim with Ctrl + Z,
play in the terminal,
then return to exactly where you left with Vim by just typing the command fg.
If enabled in your version of Vim, a terminal can be started with the :term command.
Terminal window support was added to Vim 8. It is an optional feature that can be enabled when compiling Vim with the +terminal feature. If your version of Vim has terminal support, :echo has('terminal') will output "1".
Entering :term will place you in Terminal-Job mode, where you can use the terminal as expected.
Within Terminal-Job mode, pressing Ctrl-W N or Ctrl-\ Ctrl-N switches the mode to Terminal-Normal, which allows the cursor to be moved and commands to be ran similarly to Vim's Normal mode. To switch back to Terminal-Job mode, press i.
Other answers mention similar functionality in Neovim.
:sh then Ctrl+D to get back in (bash)
Update:
You could map Ctrl+D in vim to run :sh, which allows you to toggle between bash and vim quickly.
noremap <C-d> :sh<cr>
The main new feature of Vim 8.1 is support for running a terminal in a Vim window.
:term will open the terminal in another window inside Vim.
:term
Added in Vim 8.1.
Keep in mind that whenever a terminal window is active, most keystrokes will simply be passed to the terminal instead of having their usual functions. Ctrl-W and its subcommands are the main exception. To send a literal ^W input to the terminal, press Ctrl-W .. You can also open the Vim : command line by pressing Ctrl-W :. The other Ctrl-W commands work as normal, so managing windows works the same no matter what type of window is currently selected.
Eventually a native :terminal command was added to vim in 2017.
Here is an excerpt from the :terminal readme:
This feature is for running a terminal emulator in a Vim window. A
job can be started connected to the terminal emulator. For example, to
run a shell:
:term bash
Or to run build command:
:term make myprogram
The job runs asynchronously from Vim, the window will be updated to
show output from the job, also while editing in another window.
This question is rather old, but for those finding it, there's a new possible solution: Neovim contains a full-fledged, first-class terminal emulator, which does exactly what ConqueTerm tried to. Simply run :term <your command here>.
<C-\><C-n> will exit term mode back to normal-mode. If you're like me and prefer that escape still exit term mode, you can add this to your nvimrc:
tnoremap <ESC><ESC> <C-\><C-N>
And then hitting ESC twice will exit terminal mode back to normal-mode, so you can manipulate the buffer that the still-running command is writing to.
Though keep in mind, as nvim is under heavy development at the time I'm posting this answer, another way to exit terminal mode may be added. As Ctrl+\Ctrl+n switches to normal mode from almost any mode, I don't expect that this answer will become wrong, but be aware that if it doesn't work, this answer might be out of date.

I know that I'm not directly answering the question, but I think it's a
good approach. Nobody has mentioned tmux (or at least not as a
standalone answer). Tmux is a terminal multiplexor like screen. Most
stuff can be made in both multiplexors, but afaik tmux it's more easily
to configure. Also tmux right now is being more actively developed than
screen and there's quite a big ecosystem around it, like tools that help
the configuration, ecc.
Also for vim, there's another plugin: ViMUX, that helps a lot in
the interaction between both tools. You can call commands with:
:call VimuxRunCommand("ls")
That command creates a small horizontal split below the current pane vim
is in.
It can also let you run from a prompt in case you don't want to run the
whole command:
<Leader>vp :VimuxPromptCommand<CR>
As it weren't enought, there are at least 6 'platform specific plugins':
vim-vroom: runner for rspec, cucumber and test/unit; vimux support via g:vroom_use_vimux
vimux-ruby-test: a set of commands to easily run ruby tests
vimux-cucumber: run Cucumber Features through Vimux
vim-turbux: Turbo Ruby testing with tmux
vimux-pyutils: A set of functions for vimux that allow to run code blocks in ipython
vimux-nose-test: Run nose tests in vimux
Here is a nice "use case": Tests on demand using Vimux and Turbux with Spork and Guard
Someone already suggested https://github.com/Shougo/vimshell.vim, but they didn't mention why. Consequently, when I came away from this question I wasted a lot of other time trying the other (much higher ranked) options.
Shougo/vimshell is the answer. Here's why:
In addition to being a terminal emulator, VimShell allows you to navigate through terminal output in normal and visual mode. Thus, if a command you run results in output that you'd like to copy and paste using the keyboard only...VimShell covers this.
None of the other options mentioned, including the :terminal command in NeoVim do this. Neovim's :terminal comes close, but falls short in at least the following ways as of 2/18/2017:
Moves the cursor to the end of the buffer, instead of at the last keeping it in the same spot like VimShell does. Huge waste of time.
Doesn't support modifiable = 1 see a discussion on this at Github, so helpful plugins like vim-easymotion can't be used.
Doesn't support the display of line numbers like Vimshell does.
Don't waste time on the other options, including Neovim's :terminal. Go with VimShell.
It's possible to open a new tab with a terminal in vim since 2017 as #fjardon said:
Just type: :terminal. It will open a tab by default above your current tab.
If you want it to open in another place you can try the following options:
:below terminal : open the terminal below current tab.
:below vertical terminal : open the terminal always vertically to the right.
You can play with these until you find what you like. After this you can set a map in your .vimrc configuration file, for me, I use:
nmap <leader>tt :below vertical terminal<CR>
This way I can type <space>tt (space my leader key) to open it quickly.
As a side note:
You can switch between your tabs (terminal and other buffers) with Ctrl+W Ctrl+W.
You can enter an editable mode in your terminal if you want to copy your commands with Ctrl+W N and go to normal terminal mode with i or a.
Cheers!
You might want to take a look at the :sh command (see :help sh in Vim).

By far, I have tried a lot of solutions mentioned here, what I really wanted is to keep the terminal open while coding a similar experience in VsCode. Then I came across this solution which is working perfectly for me.
Before Installing:
I am using Nvim 0.5 but I think it can work for any version and checked also on vim
I am using macOS Catalina Version 10.15.7
Setup your integrated terminal
Step -1-
Create a script with the name myQuickTerminal.vim or whatever name you want.
Put the following script
"==============================================================================
"
" ▒█▀▀█ █░░█ ░▀░ █▀▀ █░█ ▀▀█▀▀ █▀▀ █▀▀█ █▀▄▀█ ░▀░ █▀▀▄ █▀▀█ █░░
" ▒█░▒█ █░░█ ▀█▀ █░░ █▀▄ ░▒█░░ █▀▀ █▄▄▀ █░▀░█ ▀█▀ █░░█ █▄▄█ █░░
" ░▀▀█▄ ░▀▀▀ ▀▀▀ ▀▀▀ ▀░▀ ░▒█░░ ▀▀▀ ▀░▀▀ ▀░░░▀ ▀▀▀ ▀░░▀ ▀░░▀ ▀▀▀
"
"==============================================================================
" " This is a script that will trigger a terminal quickly than the FloatTerminal
" open new split panes to right and below
"link: https://betterprogramming.pub/setting-up-neovim-for-web-development-in-2020-d800de3efacd
"==============================================================================
set splitright
set splitbelow
" turn terminal to normal mode with escape
tnoremap <Esc> <C-\><C-n>
" start terminal in insert mode
au BufEnter * if &buftype == 'terminal' | :startinsert | endif
" open terminal on ctrl+n
function! OpenTerminal()
split term://zsh
resize 10
endfunction
nnoremap <leader> n :call OpenTerminal()<CR>
NOTE: if you want to run bash instead of zsh for a particular reason then replace zsh with bash.
Step -2-
Lets source it, put this in init.vim for neovim or `.vimrc' for vim
source $HOME/.config/nvim/modules/mySpecialScripts/myQuickTerminal.vim
This will be preloaded ahead as you save and resource it, you can use source $MYVIMRC for quick reloading the init.vim file.
Step -3-
I mapped as you can see in the script n to open a terminal in a new pane, my is the (Space bar) and once I click (space + n) a terminal will be triggered and I will enjoy writing my code while the terminal is opened.
To quit insert mode in the terminal, press Esc.
Now, to switch to the code editor pane, use CTRL+w w. This shortcut can get annoying once you have more than two panels open, so I added the following shortcuts too.
I mapped these too for quick jumping among opened panes, use these
" Better window navigation
nnoremap <C-h> <C-w>h
nnoremap <C-j> <C-w>j
nnoremap <C-k> <C-w>k
nnoremap <C-l> <C-w>l
Optional
If you want your terminal to exit the current buffer with key. you can use
tnoremap <Esc> <C-\><C-n>:q!<CR>
But since I want to switch in between several buffers I use without close the terminal I use instead:
tnoremap <Leader><Esc> <C-\><C-n>:q!<CR>
Final results
Reference:
https://betterprogramming.pub/setting-up-neovim-for-web-development-in-2020-d800de3efacd
Only way I know of is by using vim-shell, a third-party patch.
I use this now, you may can try. VimShell
Split the screen and run command term ++curwin to run the terminal inside the Vim buffer. Following command does both and worked for me:
:bo 10sp | term ++curwin
If you are interested in quick answer, here is it: :vert term. It will split your screen vertically and open up terminal.
Try vterm, which is a pretty much full feature shell inside vim. It is slightly buggy with its history and clear functions, and still in development, but it still is pretty good
Assuming your version of vim supports +term command first, set shell for vim to use in one command (e.g. set=/usr/bin/zsh), and then run the command +term (i.e. bo 15vs +term). you may have to do some additional maneuvering of your windows (i.e. deleting one and rotating), but you'll have your terminal.
With vim 8.1.3741, just type :terminal to start a terminal inside of vim.
Try map :nnoremap ]t :terminal<CR> to do that quicker!
I acknowledge that I am not strictly answering your question, but what has worked better for me when using Vim and Terminals in the same window is Tmux (which is kind of a "run in the background software" like, similar to screen, although this one works better with splits and tabs).
This post will help you to understand how they work together: 'Tmux and Vim — even better together'.
This way we can convert Vim into a powerful IDE
