Example, in NetNewsWire there is a keyboard shortcut to mark a page as read and a hidden keyboard shortcut that marks all items from that feed as read. I accidentally hit both often. How can I block the keyboard shortcuts from working?
There's an option to change the keyboard shortcuts, just remove the ones you don't want to use.
I believe it's in Help > Keyboard Shortcuts
hmm I haven't used NNW in a long time but now that I think about it I'm not sure if there is a way to remap the keys...
You could however use Butler (not freeware) to remap the keys but I doubt you'll want to buy software to do that...
Other than that I don't think it's possible...
