This extension for Visual Studio Code (vscode / code), developed for provide my own preferred keybindings:
[Ctrl+Shift+(←↑→↓)] - column selection
[Ctrl+a] - context-driven "select all"; when some word is already selected, it performs "editor.action.changeAll"
[Escape] - is a killing feature :); triple press Escape to close current editor, or whole vscode, when no editors opened.
