favorite keyboard shortcuts

Thought this might be an informative thread where we share our favorite keyboard shortcuts particularly those that may not be obvious...  I've been doing this for a very long time, starting in very early versions of Avid Media Composer and FinalCut 1...  I used to obsess about keyboard shortcuts, but over the last few years, I've loosened up a bit.  But whenever I'm involved in constantly using repetitive tasks, I start exploring Premiere shortcuts.  It's pretty amazing how deep and useful this feature is.  And I'm constantly discovering useful keyboard shortcuts that didn’t seem obviously available. 

For example, I do a great deal of editing on a 2012 macbookpro when I’m working at a client’s office…. It’s a severely underpowered machine that’s pretty close to end of life since I cannot update the OS beyond Cataline, so I’m stuck on Premiere 2022…. I work with low res proxies and it works fine…. When I’m doing edits for verbal content, I usually work at ¼ resolution in the program monitor for smooth playback, but often want to review it at ½ resolution after rendering a section.  After mousing to change the program monitor resolution constantly, I thought… maybe there’s a keyboard shortcut…. The search function in the keyboard shortcuts is great and I searched ¼ and there it was, as was ½.  Just mapped them to 4 and 2. Maybe those of you who’s memory is better than mine can instantly remember your shortcuts, but it always is helpful for me to use a keyboard shortcut that’s easy to remember.  I also use post-its attached to my screen….and I often change the default shortcut to something that’s easier for me to remember…

I hope this thread will be useful to both neophytes and experts.  Always amazes me how much I don’t know in Premiere….

Happy New Year everyone.
