Change shortcut to stop recording

Hello,

I am using the keyword tests and I must use the keys "Shift-F2" for my test.
When I do this, it stops the recording and my Shift-F2 is never inserted in the test.

I tried to create a new keyboard mapping scheme but it doesn't work. Strangely, the button that I see associated to STOP recording is Shift-F5.

How may I use Shift-F2 without stopping the recording?
