Some standard conventions is missing in the Script Editor:

Ctrl-C : copy selected line
Ctrl-V : paste selected line

Paste also pastes the clipboard to the line BELOW current line. I think the more common way is to paste it OVER the current line.

Cut doesn't seem to work at all.

I'd like a keyboard shortcut to insert a blank line (empty comment). (Shift enter?)

I'd like a keyboard shortcut to open properties for current selected line. (Enter?)

I'd like to be able to delete a line by hitting Del (and no "are you sure message").

Undo/Redo is a must.

These are all pretty common things to expect from an editor, and if you manage to provide them, it will be very nice to work with

I'm very impressed with the product so far, it just needs alittle bit polish here and there. And the responsetimes on the forum are just exceptional! Good work!
