Setting up Vim-like controls in GTK
I use the Vim text editor for almost all tasks related to interactive text editing: for configuration files and source code, as LaTeX, for writing letters in conjunction with mutt and even as an external editor in a web browser.
Well-established hotkeys for cursor control [hjkl] began to move beyond the editor, for example, into the command shell (in conjunction with the modifier).
However, I would like to have the usual hotkeys in graphics applications. Actually, the following discussion focuses on setting up a GTK environment.
Perhaps, many people know about the existence of gtk-emacs binders, located in / usr / share / themes / Emacs, which can be simply embedded in the GTK user configuration file. For Vim, unfortunately, ready-made recipes "out of the box" are not provided, moreover, the implementation of multi-mode is not a trivial task, so you have to do with one mode using modifiers.
')
It was decided to hang the cursor keys on Mod1 + [hjkl], the beginning / end of the line Mod1 + [wq], plus describe the classic binding of the form ^ H, ^ U and ^ W.
Without further ado, I give examples of files:
The article was based on the Vi key bindings in gtk article, which describes a similar procedure for read-only environments.
