Automates Keyboard strokes to automate tedious UI actions
|
|
|
|
Performs N keyboard key code presses

https://eastmanreference.com/complete-list-of-applescript-key-codes
|
|
|
|
Sleeps for \$SLEEP_SECS (default: 1) between clicks to allow UIs to update and perform the next keystroke
|
|
|
|
Starts each keystroke after \$START_DELAYS seconds (default: 5) to give time to alt-tab back to your UI application and position the cursor
|
|
|
|
If given num is negative, will run indefinitely until Control-C'd
