## What it is
Uncap is a tiny Windows utility written in C that maps the Caps Lock key to Escape, or any key to any other key, via command-line arguments. It is a single ~100 KB executable aimed primarily at Vim and Emacs users who want Caps Lock to act as Escape without editing the registry or rebooting.

## Use cases
- map caps lock to escape on windows
- remap any key to any key on windows
- disable a keyboard key
- change key mappings without rebooting
- make caps lock work as escape for vim
- temporarily disable key remapping

## When to choose
- you use Vim or Emacs and want Caps Lock as Escape on Windows
- you want a lightweight, no-install, single-executable remapper
- you need to change or revert key mappings without rebooting

## When to avoid
- you need per-application or complex multi-key macros and chords
- you are on Linux or macOS and prefer native tools like setxkbmap or Karabiner
- you need a GUI for managing key mappings
