Windows 10: How to undo a hotkey made with AutoHotkey

I downloaded & installed AutoHotKey Unicode 64-bit. I tried to use the basic tutorial & copied their beginner script:
^l::
Send, My First Script
return

(I used small L in place of j).

However, now I want to unassign that key & can't. Even if I delete the script, every time I press Ctrl=l, it writes My First Script. I can't find anywhere on the tutorial of how to change this back. How can I undo the key assignment?

Thank you in advance!

:)

 

Are custom hotkeys possible?

may be possible using eventghost, http://www.eventghost.org/ it has a keyboard hotkey plugin and a sound mixer plugin, so can be configured to mute mic off on i guess.
theres also autohotkey, but i havent used it.

 

Shortcuts/hotkeys for text suggestion

I didn't found it official shortcut list, so I ask here.

Are there are any shortcuts/hotkeys to

• loop though text suggestions
• insert the text suggestion

 

Disabling a hotkey in Windows Explorer

Only one way to do this is to try it out for yourself or read the feature list of the 3rd paty software Bro suggested.
