Phoenix Wright: Ace Attorney - Trials and Tribulations/Controls

The controls for this game are fairly simple, as there aren't many actions to perform and you can only do one at a time.

Nintendo DS/3DS
The DS and 3DS versions can be played entirely with Stylus besides using buttons; just point and click what you want on the touchscreen.

Windows
You can play the Windows version entirely with a left click of the mouse (right click to cancel) or with the keyboard keys listed above, which can be changed in the Preferences dialog. The game has no voice support and there are four other keys you can't change:
 * Tab: Open the System menu.
 * Enter: Select a menu item.
 * Esc: Close an open menu.
 * Alt + Enter: Switch window mode.
