F6 : How to get rid this shortcut ?

[#1]

I cannot find on Edit > Keyboard shortcuts the location of F6 to get rid of it.
Every time I try to reach F7 I hit by mistake F6 , so I need to disable this shortcut.
Thanks

Record an action that does nothing and assign F6 as its shortcut. Than  will override Adobe's default F6 shortcut.  There are Adobe shortcuts tie cab not changed or overridden like D reset swatches.  The F key shortcuts can be overridden....
