Add creating a Stamp Visible Layer as a menu command

Another option is to script the process, then a custom keyboard shortcut can be applied to the script.

If anyone is going down the rabbit hole of setting tons of custom keys, I discovered an issue with Stamp Visible vs Merge Visible.

As we know, the default hotkey for Stamp Visible is Alt Shft Ctrl E. That's not fully true.

What it actually is, is just the hotkey for Merge Visible + Alt.

So if you want to change the Stamp Visible hotkey, you have to change the Merge Visible hotkey to something (like Ctrl P or whatever you want), and hold Alt whenever pressing your new key.

How it works

New Merge Visible hotkey: Ctrl P

Means the new Stamp Visible hotkey would be: Ctrl Alt P

This is clunky, and Stamp Visible should be separated out of the Merge Visible hotkey setup, but this is how you change the Stamp Visible Hotkey.

Nothing wrong with wanting to add it to the menu. 

yep, but what's the problem to add it to the menu...

by force of habit I wanted to use the menu for recording an action

It is amazing that it is not in the menu, yet, but I think that those that use that command prefer KBSC over menu items.
