Hi there
I was just trying out the custom commands and wanted to add one. I also wanted to use 'ALT + N' as shortcut for the command. So I clicked with my mouse on the input field where it says 'Shortcut key' [
None____] and clicked on ALT + N, it worked, but I also got prompted to enter a name for a new custom command :P It also listens for shortcuts from within the dialog window you are in. Maybe it is nice (and more professional) to tweak that, so it doesn't. Because it is a bit annoying.
