## What it is
ace-window is an Emacs Lisp package for quickly selecting and switching between Emacs windows using a single key binding and labeled window hints. It also supports swapping, deleting, and moving windows, and works across multiple frames.

## Use cases
- quickly switch between many Emacs windows with one keybinding
- avoid repeated other-window calls in multi-window layouts
- swap two Emacs windows from the keyboard
- delete a specific window without using the mouse
- navigate windows across multiple Emacs frames

## When to choose
- you use Emacs with multi-window layouts and want fast, predictable window switching
- you prefer keyboard-driven window management over windmove arrow bindings
- you want window swap/delete/move actions from one command

## When to avoid
- you use a different editor or IDE without Emacs
- you only ever work with one or two windows
- you prefer mouse-based window management

## Facets
- artifact type: plugin
- maturity: stable
- function: editor, developer-tools
- domain: text-editors, developer-tools
- platform: editor-plugin, cross-platform
- tags: emacs, window-management, keyboard-driven, emacs-lisp
