Often when I'm on an instruction, I want to rename the operand to something else than the automatic label it had, because the surrounding code informs me of the (probable) meaning of the operand.

Currently, it seems like the fastest way to do this is to hit Ctrl-O for "Edit Operand", then Alt-L as shortcut for the "Edit Label" button.

However, I find myself doing this sequence much more often than anything else in "Edit Operand", so a dedicated shortcut would be helpful. SourceGen's shortcuts are otherwise very convenient, so this stands out a little.
