# Modifier Key

* Default:
* Example: `modifier_key = key_lalt`
* Since: 2.7.3dev
* Type: Choice

The modifier key is the key you use (in combination with other keys) to
trigger shortcut functions in FS-UAE. What the default modifier key is
depends on the operating system; <kbd>Cmd</kbd> on macOS and
<kbd>Alt</kbd> on other systems.

* `key_lsuper` (<kbd>Cmd</kbd>) on OS X.
* `key_lalt` (<kbd>Alt</kbd>) on other operating systems.

This option be can be used to change the default modifier key to almost any
other key.
