Some questions (green screen, keyboard shortcuts)

is there a possibility to turn off the green screen (which is shown at the beginning of my macro, when i start it)?

The green screen is used to calibrate the computer vision logic. It only shows when you have an XClick or XMove command in your macro.

how to set up the macros to run more stable or faster?

It depends what exactly goes wrong. Can you please make a new, more detailed forum post for this?

are there shortcuts (e.g. F7) to start/stop the macro or can they be set up?

Yes, please see:
