# Keyboard and mouse tips

## Mouse modifiers

These modifiers will help you play DOS games on a trackpad or one-button mouse:

Action | Shortcut
--- | ---
Click the right mouse button | `Ctrl ^`+`click`
Click the middle mouse button | `Opt ⌥`+`click`
Click the left and right mouse buttons simultaneously | `Ctrl ^`+`Opt ⌥`+`click` or three-finger tap on trackpad
Lock/unlock the mouse from the window This will also reveal the menu bar in full screen mode | `Cmd ⌘`+`click`

## Keyboard shortcuts

Action | Shortcut
--- | ---
Show/hide the Inspector panel | `Cmd ⌘`+`I`
Pause the emulation | `Cmd ⌘`+`P`
Switch to/from full screen mode | `Cmd ⌘`+`F` `Cmd ⌘`+`Shift ⇧`+`F` to switch instantly
Choose a rendering style | `Cmd ⌘`+`1`/`2`/`3`/`4`
Toggle aspect ratio correction on/off | `Cmd ⌘`+`Shift ⇧`+`A`
Skip a gamebox’s default program This will show the DOS prompt instead | Hold `Opt ⌥`while the gamebox is loading

Additional keyboard shortcuts can be found alongside each item in Boxer’s application menus.

## Using function keys on a Mac keyboard

The `F1`–`F10` function keys are normally reserved for OS X system functions like Exposé and Dashboard. To make these keys work normally in DOS, hold down `fn` as you press the function key.

This behaviour can be toggled from the OS X Keyboard preferences pane.

You can also send function key signals directly to DOS using the Emulation ▸ Send Key menu.

## Preventing arrow-keys from switching OS X Spaces

The default OS X keyboard shortcuts to switch Spaces are `Ctrl ^`+`⇠`/`⇢`. These can interfere with games that use the arrow keys and `Ctrl ^` as an action button. You can change or disable these shortcuts:

- In OS X 10.6 and below, via the Exposé and Spaces preferences pane.
- In OS X 10.7, via the Keyboard preferences pane instead.

## Can’t find a particular key?

Boxer emulates an MS-DOS PC keyboard layout, and special characters (such as punctuation) are often in different places than where they’re labelled your Mac keyboard.

You may have to try nearby keys and `Shift ⇧`-ed keys to find the character you’re looking for. On non-US keyboards, you can also hold down the right-hand `Opt ⌥` key to access additional special characters.

Some keys found on a DOS-era PC keyboard, like Insert and NumLock, don’t exist at all on a Mac keyboard. If you have a game that needs these keys, you can send them using the Edit ▸ Send Key menu.
