GNU Screen refresh problem - gnu

I've recently started using GNU Screen but have run into a very annoying problem.
In any screen window if I press the left arrow key or backspace when there is nothing typed at the prompt the screen seems to refresh, causing a slight flicker. After typing some text at the prompt using the backspace or left arrow won't cause the flicker (at least until the first character in the prompt is reached).
Anyone seen this before?

That's not a problem. It's a feature. It's supposed to behave like that when "visual bell" is enabled in your terminal. Which it is, by default I guess.
Take a look at this document. There are three properties in the file that relates to visual bell. You can change that in ~/.screenrc
vbell_msg "bell: window ~%" # Message for visual bell
vbellwait 2 # Seconds to pause the screen for visual bell
vbell off # Turns visual bell off
Try setting vbell property to off.
Also, I would recommend you ask the same question in ServerFault. I am sure you'll get way better answers over there. To access the site, since it's in private beta, check this blog entry.

Code snippet floating in mid-air as a tooltip, cannot hide it, after extracting method [IntelliJ Idea / Android Studio]

Trying to perform the Ctrl + G (Go to line) keyboard shortcut, seems I accidentally activated a feature that pins the code the cursor was previously on.
After closing and reopening the file, things are worse; the code snippets still are floating over the screen, no matter if I move the Android Studio window.
I have searched keyboard shortcuts using this guide, but no luck.
Is there a way to disable or revert this?
Noticed by comment below and confirmed by myself: This happens after extracting a method.
I have been able to get rid of those permanent tooltips by invalidating caches and restart, but this should not be the way to disable them, as I still don't know which is the keyboard shortcut to toggle this "pin snippet" function.

How do I completely disable bell in screen (both visual and audio)

In screen, is there a way to completely disable bell ?
I know you can switch to audio bell instead of the visual one and have already done that and have also specified no bell in putty so I don't hear anything but whenever there is a bell in one window, I see an annoying popup on the other windows say "bell in window 1" and so on.
Any idea on how to get rid of it ?
To permanently disable the visual bell, you need to add the following command to your .screenrc file:
vbell off
I haven't tested it, but adding the additional line to your .screenrc file should disable the message bell:
bell_msg ""
To disable it in a session (temporarily, not permanently), issue the following command from the session:
CTRL+A, CTRL+G
See the man page for screen (section 'CUSTOMIZATION') for more information.

Visual Studio: Undo-redo of replace-action does not scroll editor window

I did some find-and-replace actions in my C++ code with visual studio:
only single find-and-replace actions (did not use “replace all”)
only one file affected (did not change multiple files at the same time)
thus, a very simple case!
Then I wanted to undo these changes. So I pressed ctrl-Z one time. This had the desired effect. The latest change (which was still visible in the current screen) was undone.
But I also wanted to undo the remaining changes. These changes where currently not visible on the screen. So I expected the editor to scroll there when pressing ctrl-Z.
But unfortunately the editor did not scroll to the position of the undo when I pressed ctrl-z.
The undo worked, however. I checked by scrolling to the position manually.
Then I tried it with redo. Same result: Redo worked, but the editor did not scroll to the position of the redo.
Finally I tried if this also happens when I undo-redo other types of changes (not made by the “find and replace” functionality).
Result: Undo-Redo worked correctly and also scrolled correctly!
Thus: It seems only changes by the “find and replace” functionality are affected by this problem.
Did you also have this problem and found a solution?
Please help me!

I am having the same thing happen in Visual Studio Ultimate 2012 (Version 11.0.60610.01 Update 3).
It might sound like it's not that important, but it is really hurting the usability of this otherwise great IDE!
PS I've been using VS since the 90s, I still haven't found anything better. I wish MS would put macros back into VS, even if it's VBA (or Python)

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.

Whack vim screen drawing errors

Something extremely weird is happening when I open files in vim, and I can't remember doing anything that would have caused it.
Weird behaviors include:
no text being visible until I highlight it in visual mode, at which point it is visible from thereon. ":redraw!" does not make anything visible.
line 1 missing
occasionally the cursor appears one line below where it is editing
statuses become permanent and scroll up from the bottom, rather than just redrawing at the bottom
the vim text not extending to the bottom of the vertically maximized window
I lack the reputation to post screenshots but I'll happily provide any other information that could help in a diagnosis.
ETA: Ah! My .vimrc specified a column/row size. I've removed that line, and so far things are behaving well. Thank you!
vim is terminal based, and errors like this happen when the terminal you are using does not match the terminal vim thinks you are using. Most people use vim with terminal emulators. This kind of thing can happen when you resize the emulator window and vim does not find out about it, or more rarely, when the terminal-identifying-string specified in the environment does not match the terminal emulator you are running.
Without more details about the platform on which you are running vim, it is hard to be more specific-- but as a tip: don't resize the emulator window after it is created but before running vim.
Terminal emulators are supposed to communicate size changes back to the program running within them, but this is not 100% foolproof, especially when you are logged in to a remote machine within the emulator.
If you're doing this from a UNIX (Linux et al), try running :!resize to force your terminal to re-adjust its size parameters. At the very least it'll tell you what the system thinks your window is sized to, which may not match its actual size.
I had a similar problem when using vim with bash. When I switched from bash to zsh, it gave redraw errors where, while I typed, the cursor or screen would appear to go down one row for every 10 characters I typed. Scrolling with arrow keys also caused major display problems along the same lines, but worse.
I had this line in my previous .vimrc, I believe it was to set the color for vim
set t_256
I changed it to set term=xterm=256color and the problem went away.
