3. Sending keys to device and assigning gestures
Once step 1. is complete, and the device has successfully connected to the computer, the “Configure device” menu item in PadD will be enabled. This allows the user to assign custom images to keystrokes, by dragging an image from Finder into the image box and setting a keyboard shortcut by clicking the white text field and pressing the keystroke. One can also edit modifier flags after entering the keystroke simply by pressing the corresponding button below the text field.
It is recommended to “split” your keystrokes into the actual key to press and then manually adding the modifier flags desired with the buttons. This is because Mac OS as well as some applications sometimes “steal” the keystroke, depending on if it’s an application shortcut or a system-wide hotkey. Assigning application-specific keystrokes, such as Copy (⌘+c) should work by simply pressing the text field and pressing ⌘+c. However, if one desires to activate Spotlight (⌘+space by default), pressing the keystroke will cause Spotlight to activate, and PadD will not register the keystroke. This is fixed by pressing space first, and then selecting the ⌘ button below the text field. The key/gesture is assigned by pressing the “Send to device” button. It is possible to just set modifier flags (ctrl, alt, cmd, etc) to keys by not typing anything in the text field.
