🛠️ Editor Keymaps

I organize keyboard shortcuts into 4 categories:

1. HJKL with ⌘⌥⌃⇧ modifiers.
2. Vim Leader Key mappings.
3. Vim commands. e.g. ⌃ + w for window managment.
4. Standard shortcuts, e.g., ⌘ + t to create a new tab and ⌘ + w to close one.

Not only does it allow me to remember over 200 keyboard shortcuts, but it also lets me work (almost) the same way across editors:

WebStorm (and other JetBrains IDEs) with IdeaVim plugin:

• .ideavimrc

VSCode with VSCodeVim extension:

• settings.json (Vim key bindings)
• keybindings.json

Zed with built-in Vim Mode :

• keymap.json

HJKL with Modifiers

HJKL are not only ←↓↑→ for Vim. I use them with modifiers for any directional actions like moving, scrolling, navigating back/forward, tc.

Across Apps

Some common commands, like going back/forward in history (⌃ + h, ⌃ + l), are also used on other apps, such as browsers, via Karabiner-Elements .

Home Row Modifiers

I use 2 keys on the home row (or below) for modifers via Karabiner-Elements , e.g. s_f (pressed and held at the same time) for ⌃, so s_f + h for “Go back”, all keys at home row.

Scroll up/down in file

In Vim ⇧ + j join lines. I remapped ⌃ + y for it instead.

⇧ + j

⇧ + k
