Mapping TO ctrl+[something] doesn't work in gvim - vim

I am using GVim 7.4 and I would like to do some really simple mapping to use CtrlP fuzzy matching of tags when a key combination is used.
I tried 2 approaches and they all seem to fail when vim calls Control + [x] combination. While I do understand that there are restrictions when it comes to mapping Ctrl+[x] codes, I haven't found any information on why ctrl mapping wouldn't work.
noremap \t :CtrlPTag<CR><C-\>w
This one enters CtrlP tag mode but then it doesn't enter word from under the cursor.
noremap \t <C-p><C-\>w
Here we don't even get to CtrlP window (I even omit going into tag mode here for simplicity).

As far as I understand (I'm no CtrlP user), the plugin is triggered via some command / key combination, and then presents interactive selection and filtering. It even has different "source" modes.
Now, this is a pretty heavy integration into Vim, probably using scratch buffers and its own input loop. That's why you cannot simply append keys to the mapping and get them interpreted by the plugin "as typed".
Typically, these plugins offer mode selection and so on via (optional) command arguments. Check the plugin's help, and if you cannot get the plugin into the state you need, best contact the plugin's author and ask for such enhancement.

Use AHK to detect the "Vim Mode" for GUI windows and configure conditional mappings of keys

The motivating story (TL;DR)
Terminals, due to historical reasons, won't distinguish tab from Ctrl+I. This makes quite a mess when I use Vim: my muscle memory tells me that Ctrl+I shall advance me forward to the next position in the "Jumplist", but some Vim-plugins do remap the tab key to do other good stuffs.
Better defined task
Can I make a "conditional mapping" for active windows from ahk_process gvim.exe when no "special characters" are shown at the bottom left corner of the active Window?
For the window on the left, the Vim session is in "Normal-mode"
For the window on the right, the Vim session is in "Insert-mode".
Other modes do exist, like Visual-mode
At the end of the days, I would like to map the tab key only in "Normal-mode". The best that I can come up with is to OCR a fixed region of pixels at the buttom-left corner, and make it a conditional. Yet, I am inexperienced for getting OCR jobs done in AHK.
Sidenote: I am asking for help from the Vim community the flipside of the same question: https://vi.stackexchange.com/questions/18796/may-i-have-a-vim-session-report-its-mode-in-its-window-title
No need for OCR/AHK hacks.
:nmap (and :nnoremap) maps only in normal mode.
:imap (and :inoremap) maps only in insert mode.
etc.
See :help :map-commands for the variety of different mapping commands for variety of modes.
If a plugin is overwriting a normal-mode mapping for Tab, see who the offender is by using :verbose nmap <Tab> (or its equivalent, :verbose nmap <C-I>), then look at its documentation to see how to rebind it (or in the worst case, eliminate the culprit).
There's no need to grab Vim's current mode to make it available to another application; that would be really cumbersome. If your eventual goal is to send different keys for <Tab> / <C-i> to Vim (e.g. <F13> instead of <Tab>), and you only want Vim to react differently in certain modes (e.g. normal mode), you can just map the other modes to again unify both keys:
:nnoremap <F13> ... " Functionality A
:nnoremap <C-i> ... " Functionality B
:map! <F13> <C-i> " Both keys continue to do the same in insert and command-line mode.

vim - navigating characters in command mode

Relatively new to VIM and having a great time using it.
One very minor annoyance I've been having is command mode character navigation when I want to revise a command. I'm used to using readline shortcuts on the regular (non-vim) command line but these shortcuts don't seem to work in : command mode.
For example, using ctrl + b to go back a character ends up sending me to the start of the line, or using alt + f to go forward a word ends up clearing the line and exiting command mode.
The only way I've found to navigate in command mode is to use the arrow keys, but I'm under the impression you should avoid the arrow keys in vim for max efficiency.
What is the standard way to navigate around in : command mode? Do vim users usually use the arrow keys here? Is there a different way to modify commands?
As a more concrete example, I've been using vimgrep a lot to search through files. I'll do a command like:
:vimgrep /font-family/j my-project/**/*.less | cope
Later, I'll want to use the same search but look for a different property, so I hit : then ctrl + p to access my previous vimgrep. Now here I have to use the arrow keys to navigate backwards to the search string and modify it. It would be much faster if I could use readline to navigate backwards by word then delete by word.
For small edits, Backspace and light use of the cursor keys should be fine. For anything larger, I would advise to use the command-line window:
In the command-line window the command line can be edited just like editing
text in any window.
So, there's no need to mentally switch to readline key mappings; just use the full editing power (including any custom mappings) of Vim!
You can switch via <C-F> from the command-line, or directly enter it (from normal mode) by pressing q: instead of :. All the details can be found at :help cmdline-window.
I like this question. Long time vim user, but new-ish here, so I can't vote it up. But indeed, perhaps unofficially, many vim fans feel that most of the time the goal is to not have your hands leave home row position (fingers move, hands relatively still).
I will admit, when it comes to command mode, I use the arrows. With P being on my pinky finger, I would miss-hit ctrl-P a lot, and it's faster to slide my right hand down (on my Natural keyboard) and find the up-arrow by quick feel, instantly, to do the same thing. Once I'm there, left-right arrows are also easy to find without looking or delay. Also Ctrl-arrows let you skip by word.
One of the great things about vim is the :help. I have easily spent tens of hours over the years reading through it, and it solves 95% of my problems if I have enough time and working-memory to push deep enough into it.
Here is what I found for :help readline:
READLINE readline.vim ft-readline-syntax
The readline library is primarily used by the BASH shell, which adds
quite a few commands and options to the ones already available. To
highlight these items as well you can add the following to your
|vimrc| or just type it in the command line before loading a file with
the readline syntax:
let readline_has_bash = 1
This will add highlighting for the commands that BASH (version 2.05a
and later, and part earlier) adds.
Give it a try! (I am using vim 7.4)
You can see a list of the default key binds with :help cmdline-history (scroll down a bit) and :help ex-edit-index.
You can remap this with cnoremap:
cnoremap <C-b> <Left>
cnoremap <C-a> <C-b>
" .. Probably more
Note that using cmap will probably get you into problems here since the right-hand side is the currently mapped action, whereas with cnoremap the right-hand side it will always use the native Vim action.

How to map keys for IdeaVim's normal mode to editor's action?

I am using JetBrains' phpstorm with the IdeaVim plugin.
I am wondering if I can bind keys in normal mode to editor actions.
For example, I used to have mapped Ctrl+B to Navigate > Declaration. Yet Ctrl+B is a vi motion to go one page backwards and that is ok.
I know I can configure a keyboard shortcut to a different one, e.g. Ctrl+Shift+B , yet to keep things simpler I want to have a key in ideavim's command mode mapped to that functionality, e.g. ;.
So that pressing ; in command mode would trigger the action of Declaration witin phpstorm.
How can I achieve this?
To give a specific answer for exactly what you asked to map: put this into your ~/.ideavimrc:
nnoremap ; :action VimGotoDeclaration<CR>
To find the action name, I typed :actionlist declaration which gives a subset of action names that include the word "declaration" in the action name.
As others have noted, you might also prefer to use one of the existing mappings rather than adding a new one.
what you wanted go to declaration is built in command in vim. You don't have to use IDEA's actions.
gd (goto declaration) is the thing you are looking for.
So you just press (normal mode) gd, to see what is gonna happen.
In a normal vim, do :h gd to check details.
You can use <C-]> (Ctrl+]) for following references (jumping to the declaration is an example of a reference) and <C-O> for going back. You can also map these Vim-style shortcuts using the map commands similar to the original Vim.

Changing default key bindings in vim

After attempting to use vim a number of times, I'm always been put off by its default key bindings. After some research, I decided to remap the default keys to more sane ones (at least for my tastes). I have a few questions about changing bindings that I could not find answers to through Google.
Is there a way to map a key to an action rather than another key. For example:
:noremap a h
will bind the a key to move the cursor left. Is there something along the lines of
:noremap a move-cursor-left
or
:noremap a :move-cursor-left<Enter>
so I can read my config file afterwards?
Is there a way to unbind all of the default key bindings? I've tried :mapclear but it doesn't seem to work, although it might just be clearing non-default bindings. Unmapping every key manually is not an option. If possible, I would like to export the defaults to a file so I can edit them as I need.
Is there another language I can use to write my own commands for vim other than vim-script? I haven't actually looked into this one so much though. If I can bind an external executable to a command, that would be good enough.
I haven't given up on vim although I would like to ask if there are any vim-like alternatives out there. My Google searches came up with nothing actively developed. If the above cannot be done, or reasonably hacked together, I would like to find a fully configurable, modal, command line text editor that can.
The command set of vi / Vim has 40 years of wisdom encoded into it; completely changing it is a bad idea. I can only repeat the reference to this answer from the comments; that should convince you (to accept this, or choose another editor).
Give the default commands another try. It'll take some time to get used to, but most Vim users swear by these. It's fine to make minor adjustments "for personal style": careful evolution, but not revolution. Also, some people with odd keyboard layouts (like Dvorak or Colemak) swap several keys for convenience.
The move-cursor-left is just h; aided by the excellent :help, you should be able to "read" your remappings just fine.
In general, even though it's possible to write extensions / plugins in integrated languages like Perl, Python, Ruby, etc. (based on support for them compiled into the Vim binary), you won't get around learning some key Vim internals and parts of Vimscript. If you don't feel comfortable at all about this, I'd suggest to use another editor. Unfortunately, with your requirements of full extensibility (and probably broad acceptance and platform support), there's only one serious alternative: Emacs (which cannot only be turned into everything but a kitchen sink, but also into a modal editor, too).
(i know this question is old)
you can reset the binds by just over-writing them
on vim you can use many <things> (idk the name)
e.g.
<Up> = Up-arrow-key
<C-f> = Ctrl, f
<A-Down> = Alt, Down-arrow-key
<Esc> = Escape-key
it's possible to remap the hjkl keys to wasd like this:
nmap w <Up>
nmap a <Left>
nmap s <Down>
nmap d <Right>

Vim: Is it possible to bind a key to open search (i.e. put me in the command mode having entered a slash, but do not type anything)

While vim's way of doing things is generally good, I feel like there are aspects that really get in the way as somebody who is not completely committed to vim for text-editing.
This means that I am hitting Esc+/ and typing slashes into files in Sublime Text, and hitting Ctrl+F in vim, scrolling down a page.
Similar things happen with Ctrl+S and :w and custom mapping ; to : still doesn't make it as convenient and fail-safe as Ctrl+S. Not to mention in PuTTY, Ctrl+S does something rather upsetting (it suspends output from the terminal till Ctrl+Q is pressed). Basically, IMHO some things (like switching to a "find mode" and saving the file) are good to attach to a global left-hand home-row shortcut chord rather than requiring the user to mess about in a modal command line. It simply is too often used to subject the user to these mode changes. I suppose this isnt a legitimate complaint because the entirety of vim is constructed around the modal concept, and these functionalities are a result of that.
In any case I'd like to make it a bit easier on my brain because I've tried for a while now to keep it all intact and it's simply too much (I have more or less internalized the switching between Ctrl on a windows machine on a desktop keyboard and the use of the thumb for the Cmd on my Macbook, but this modal text editor business seems to be too much). It did not take too much deliberation for me to decide that global homerow key chords are simply more intuitive.
Mapping Ctrl+S to :w is trivial, so the question here is about the find mode. I want to bind Ctrl+F to put me in find mode, but repeating it should not type slashes into the find command. Can this be done? Is there perhaps a colon-command that when executed simply drops me into the current find-command-buffer-thing?
In your .vimrc add:
inoremap <C-f> <Esc>/
noremap <C-f> <Esc>/
In whatever mode you are in, this will put you in "find" mode (it actually just types a slash in the command line which you can use to search). With these bindings it will work for all modes, even if you are in insert mode.
do you want this?
nnoremap <c-f> /
if you like you can also try
nnoremap <c-f> q/
the 2nd mapping brings you to a search history window. you could choose previous search keywords/patterns. also available to type new pattern (by pressing i)
btw, there is no find mode
Mappings can be defined separately for the different modes in Vim, see :help map-modes. This automatically takes care of your proposed <C-f> mapping: Initially, you're in normal mode, then the search pattern is entered in command-line mode.
If you so far only occasionally use Vim, and find it too "different", several things may make the switch easier:
easy Vim (evim or vim -y) defaults to insert mode
on Windows, :behave mswin and the $VIMRUNTIME/mswin.vim script create some common Windows shortcuts
graphical GVIM has menu items like Edit > Find... and toolbars.
Some things like the flow-control freeze on <C-s> in terminals are unfortunate, mostly historical accidents; you can't blame Vim for those.
You don't need to map anything. / is expressive enough and is definitely not slower than <C-f>. Same for <C-s> which, despite a certain familiarity, is not much better than :w<CR>. You are learning a new tool, remember?
What you should focus your efforts on is getting confortable with Vim's modality. The simple fact that, for you, doing a search involves hitting <Esc> is a sign that you didn't get that part. Your other comments on using Vim shortcuts in ST and ST shortcut in Vim are not good signs either and the part where you complain about having to adjust to your Mac's Cmd is the icing on the cake, IMO.
It may sound brutal but, from your question, it seems like you are doing too much at the same time, without organization and for, probably, no good reasons.
Switching from Windows to Mac OS X and switching from ST2 to Vim at the same time is sure to be confusing and I suggest you slow down a little and make a choice before you loose your mind and waste more of your time.
Which leads me to this: Why do you use a Mac and why are you using Vim?
Windows is a fine OS. Sublime is a fine editor. Even if you switch to the Mac, Sublime works very well there. So Why Vim?
If you are tired by some Sublime limitations and want the awesome power of Vim, fine. But you must wrap your head around its modality and awkwardness and accept to change your habit.
If you don't approach Vim with more flexibility, you'll never get full benefits.
If you decided to use Vim because it is trendy, I'll respectfully suggest you to stop there and go back to Sublime. Vim is weird, Vim is different, Vim is huge, Vim is a rabbit hole… if you are not ready to work with it and insist on not accepting its core design, you won't get far so why bother? You can pretty much live all your professional carreer without ever touching Vim. There's no shame in that.
Remapping / to <C-f>, on the other hand…
