if your keyboard supports the keySstroke technique, use the way shown in the ↓graphic↓ or ↓↓video ↓↓
→highlight →F6 →hit your desired key combination →seperate i.e. 12 to "1 & 2″ → [OK]

  How to test your keyboard  →hit from different positions [M|;]  ok →m,m,m,m,m,m,m,m,

if your typed string is different from m,m,m,.......
set up 2 shortcuts for the same action(s)  i.e. 1 & 2 + 2 & 1
to do this in the fastest way  →set up 1 & 2 →click the H tray icon →copy the 3rd last line into the empty line above and change the numbers/characters   ↓
~2 & 1::
~1 & 2::
run http://1mm.de
return

another solution is to hit the keys a little more controlled, means, the 1 key a little earlier than 2

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.
