A few tips for AutoHotkey. Pick one organizing system for your hotkeys and stick to it. Some variants:
1. collect all hotkeys in a single .ahk file. You can then simply open the source and look up all hotkeys there. Search for "::" to look up hotkey definitions e.g. "^k::".
2. Separate files, but all hotkeys for one application or window in one .ahk
3. Separate files, but put the hotkey keys in the filename. For example "Firefox copy URL (ctrl+K).ahk". If consistently done then you can search for a hotkey with Everything or similar file search tool.
4. Use a plaintext search tool like ripgrep
to instantly search the contents of a whole folder of .ahk source files.
5. Use this script
to show a list of all currently running AutoHotkey files.
