3 aims + one after another key shortcuts via the advanced GUI

requiered UNIQUE strings ≥ 2 char -_- use speciaal char. prefixes or sufixes or substitute letters with numbers A→4 I→1 E →3

the advantage from the "one after another key" shortcuts

there is no additional output from the 1st pushed key, because all typed stuff will disappear.

by triggering actions with 2 keys together you will get the 1st character, if the cursor is placed in input fields.
But you can prevent this by clicking outside the input field.
