Apple spellchecker is very useful, but does not work very well for technical text as it is missing all brand names and 50% words, doing more damage than good.
Is there a way to do "Learn spelling" action as a keyboard shortcut, so that I don't need to go through painful learn spelling right menu click every time. This starts to hurt after it is miscorrecting 100th word.
EDIT: Tried to add shortcut, but doesn't seem to work:
