Show input keystrokes in Vim - linux

When I installed Vim on Windows, it (specifically gVim) used to show to show me the keystrokes I am currently entering in the bottom right corner of the screen.
But now I'm working with gVim on Linux, and it doesn't show me.
Is there a setting (:set) I need to turn on to do this ?

The option you're looking for is showcmd.

Mouse scrolling in vim scrolls terminal window

I am just getting started using Vim and came across :set mouse=a which I've found really useful for navigating a file, however for some reason when I try and scroll now it scrolls the whole terminal window and not just the vim window.
Then I scroll up and can see the terminal outside Vim
Any ideas on how to fix this? I've tried resetting mouse= and exiting and re entering vim.
The problem was that I had accidentally disabled Allow Mouse Reporting in error.
Checking Menu > View > Allow Mouse Reporting or Cmd + R has fixed it!
I think the cheap answer to your question is that you should be navigating through files in vim using motion commands, Ctrl + d, etc. It might seem slow at first, but it really becomes more natural down the line.
That said, if you are on Mac and using Terminal, you might need to hold the Fn to temporarily disable mouse support. (Check this out for reference: OS X Terminal Mouse Support
Also, you can always try MacVim, which supports mouse scrolling out of the box.
If neither of those solutions work for you, some more information would be helpful for troubleshooting, e.g., your operating system, recent changes to your vimrc, etc.

How to Split Screen Emacs and Terminal

everyone.
I use PuTTY and I am wondering if it's possible to open an emacs text file in split screen with the terminal window.
I looked everywhere for the answer, but all I've found is how to have two emacs windows open, and I would like to be able to see and switch between the terminal window and an emacs file.
Thanks.
You could use the region feature in screen rather than using the split screen within emacs... but then you might want to rebind the escape key in screen.

Focus follow mouse in vim

I am aware that the mousefocus option is only supposed to work in gVim. But I was wondering, if it's possible to have the console Vim switch to different windows in response to mouse clicks, would it be not possible to easily add following mouse movement to it, too?
I'm an xmonad user, I love the focus following the pointer feature, I do a lot of pdf viewing and browsing while writing in Vim, and I'd be so much happier if I didn't have to keep mentally switching back and forth between two different types of focus changing.
If that's completely not possible, I guess opening new Vim windows (as with :split) in new instances of the terminal is no easier to do?
It would not be at all simple to add this. Using the mouse within the terminal works by vim sending control codes to the terminal requesting that mouse actions be sent as part of the input stream. Terminals only report clicks not changes in the pointer position, so vim has no way of knowing where the mouse is.
With major changes it would likely be possible for a vim with X support to get pointer activity directly from the X server, but that would likely be reported by pixel rather than by character so further work would need to be done before it could determine which vim window is currently under the pointer.
set mouse=a
should do the trick but it will probably depend on your terminal emulator. See :help 'mouse'.
This works for Windows 7/Cygwin 32bit mintty/vim 7.3: (I DO NOT use gvim!)
Having installed this: http://ehiti.de/katmouse/, I can scroll the window under my cursor without having to have clicked to select a window, click-selecting of single vim-windows works, too. It does not pull the vim window to the foreground, if another window overlaps it, if that is what you desire. Still it can be scrolled without click-selecting it first.
So:
Check if there exists a software paket for your distribution, that implements your desired mouse behavior on the OS level. When this works for my self-compiled vim in cygwin, it might very well work with console vim on linux, too.
This post here serves as evidence, that it is possible at all, that is the reason this was not made a comment. When I am on linux again I will investigate this further and update this post, but that might take a while.
On set mouse=a: The vim help states you a need a terminal capable of handling mouse inputs, further information can be found here. :help ttymouse might also be helpful, i.e. if you have a xterm-compliant console, but :help term is set to something else.
UPDATE: (Freshly installed Fedora 19 with packages, no self-compiled stuff.)
Fedora 19 + se mouse=a = scrolling in single console vim window with several buffers opened next to each other independently works, too. Window manager used is LXDE.

In Vim, why doesn't my mouse work past the 220th column?

I tend to maximize a terminal to one screen, and vertically split several windows in Vim. Everything works fine for the first few windows on the left, but clicking past about the 220th column in the terminal doesn't work correctly. Any mouse clicks past column 220 seem to be wrapping around to column 1. I've tested in xterm, urxvt, and Gnome terminal with and without tmux/screen; always the same behavior. If I greatly increase the size of the font in Gnome terminal, I can click on the last column (although it is no longer past column #220).
If I run a command in a terminal that prints to standard output, I can click all the way to the right of the terminal. The problem does seem to be related to Vim.
I have set mouse=a in .vimrc. I'll post the entire file on request, but it doesn't seem to have anything else related to the mouse.
It's probably irrelevant, but I'm running Xmonad+Gnome. Thanks in advance.
This has been fixed in Vim 7.3.632. See :h sgr-mouse. Or just put this in your ~/.vimrc:
set ttymouse=sgr
If you want to be compatible with versions that don't have mouse_sgr compiled in, use:
if has("mouse_sgr")
set ttymouse=sgr
else
set ttymouse=xterm2
end
To see if your version of Vim has mouse_sgr, run vim --version from the command-line, or in Vim, enter :version, and look for +mouse_sgr.
If you're using older versions of screen, or terminal emulators that don't support SGR, you may need to upgrade or switch. These settings work with all new versions of screen, tmux, gnome-terminal, PuTTY/KiTTY, iTerm2, and Terminal.app, using TERM=xterm-256color or screen-256color.
Update: If you're using neovim, SGR support is enabled by default.
Edit:
I deleted the bug report, as that tracker was for the website, not the text editor.
In looking in the correct place for an existing bug report, I found this:
http://groups.google.com/group/vim_dev/browse_thread/thread/4c137e64d2032441/b3993eaa89589619?lnk=gst&q=mouse#b3993eaa89589619
To summarize, it was an xterm limitation that has been lifted. However, Vim does not yet support columns longer than 223.
Original:
This seems to be a bug, as supported by comments made by redstreet. I filed a bug report:
https://sourceforge.net/tracker/?func=detail&aid=3389331&group_id=27891&atid=391887
A few years later, the bug still seems to be present.
The solution I found is neovim: a modern refactor of vim. Among other features, this bug has been resolved.
I simply copied my .vimrc into .nvimrc, and my plugins just worked with nvim. Maybe I'll just keep using that.

How do I get the terminal within GVim to react to mouse scrolls?

I'm on a Hardy Heron Ubuntu build, BTW.
Try:
:set mouse=a
":help mouse" says
Enable the use of the mouse. Only works for certain terminals
(xterm, MS-DOS, Win32 |win32-mouse|, qnx pterm, and Linux console
with gpm). For using the mouse in the GUI, see |gui-mouse|.
The mouse can be enabled for different modes:
n Normal mode
v Visual mode
i Insert mode
c Command-line mode
h all previous modes when editing a help file
a all previous modes
r for |hit-enter| and |more-prompt| prompt
A auto-select in Visual mode
Normally you would enable the mouse in all four modes with: >
:set mouse=a
When the mouse is not enabled, the GUI will still use the mouse for
modeless selection. This doesn't move the text cursor.
Hate to give this answer, because it isn't very helpful, but it works fine for me (scroll wheel in gvim on ubuntu hardy).
But maybe I can suggest some things that help debug the issue:
Confirm you are running "gvim" and trying to scroll the new window that comes up (i.e. you are not running vim in an xterm and trying to scroll that with the mouse)
Confirm the scroll wheel works in other apps. Use "xev" to make sure the X server is seeing the scroll events if you're unsure.
Hope that helps.
