Subject: [PATCH] main: add swipe direction keys to make debugging easier

For me with vscode triggering a breakpoint during a mouse swipe event
handler freezes all interaction with the IDE.

As a workaround (and a nice way to play `Twos.h` :D ) map the direction
keys to the corresponding swipe events.

 - `i` ... take screenshot
 - `I` ... start/stop Gif screen capture
 
+Additionally using the arrow keys the respective swipe gesture can be triggered.
+For example pressing the UP key triggers a `SwipeUp` gesture.
