Hotkeys are short key combinations that trigger a command. They're just an alternative to using the mouse, but many people find them faster and less distracting. For example, Windows uses "F1" to call up Help for the program you're currently using, and CTRL+ALT+DELETE to summon the task manager in Windows XP onwards.
You can define hotkeys for several of PTFB Pro's main functions, and for manually triggering macros and single-press items. The dedicated "HotKeys" page shown below (Options menu -> Configure... -> HotKeys) is the easiest place to view and change all the hotkeys for PTFB Pro.
Before you get started with your own hotkey definitions, please note the following:
The hotkeys page is split into two sections. The upper section deals with PTFB Pro's functions. For example, you can define a hotkey to toggle PTFB Pro between enabled and disabled, or to run the currently selected macro. The lower section is dedicated to the macro and single-press items you've created. You can define a separate hot key for each item that triggers it on demand.
To define a hotkey, just double-click the appropriate function or item and then type the key combination into the resulting screen. If the key combination isn't available, it'll be ignored. Once you type a combination that is available, it'll be set automatically. If you want to clear a combination, select it in the appropriate list and hit the adjacent Clear button.
