Robservatory:
macOS ships with ⌘O (Open) and ⌘P (Print) as pre-assigned keyboard shortcuts in Finder. Select a bunch of files to open, reach for the O and miss by just a touch, and you’ve started a dozen print jobs. Whoops!
Years ago on macosxhints.com, there was one of those “duh!” tips with an easy solution to this (and other similar) issues: Reassign the stock keyboard shortcuts.
I was constantly hitting Command-Q instead of Command-W in Safari until I reassigned the shortcut.
I’m sure I’m in the minority here, but in the early days of Mac OS X Apple briefly had an “Inspector” instead of Get Info. It was the same window, but floated and followed the current selection.
I absolutely see why people would want two Get Info windows at once, but most of the time I’m looking at Info for one thing, then Info for another thing. Once I got over my knee-jerk reaction to hating the change, I liked it.
Then Apple changed it back.
So I redefined some keyboard shortcuts:
Just like that, I have the inspector back as the “default.” The menu bar recognizes this change, too, and offers Show/Hide Inspector unless I push the option key.
I have a bunch of critical apps I’ve changed from Command-Q to Command-Shift-Q. It’s a lifesaver when you go to hit that W and hit Q on accident.
