I haven’t seen this mentioned anywhere, so just posting this in case someone would benefit from it.
For most (though not all) types of items, you can select the first one, Ctrl/Cmd-click to select the last one, then use Ctrl/Cmd-Shift-A (Select More) to select all items within that range.
Huge time saver!
Guilty as charged 
Yes! (The title of this thread should be “Select More” range. When will I get my TL3 back?)
@dan_kreider I’m glad you made this thread. I hadn’t seen @pianoleo’s previous mention of this. I had no idea this was a thing. Funny how all these little things can slip by.
Would be great if this (and the select more) would also work vertically.
Another way’s it’s useful is if you want to select passages in a score on non-adjacent staves, you can select the end points on multiple non-contiguous instruments and it will select everything in between on just those staves.
