Clicking key on piano roll to select all note on that key.
Something might already exist similar but i’d like to see this for speedy workflow… Plenty more lil things like this i’d like to see but I always forget what they are. Always pop up when I’m trying to do something.
ctrl/cmd click.
That’s a useful one that slipped by me. 
Amazing… Thank you! This is why i love Cubase, they’re always one stop ahead, thought of it already, one just needs to know what button to press. Thumbs up, thank you given!
Like I’ve just learned the tab key in vari audio… Essential button.
Can’t you shift-double click on the note, and all successive notes are selected for that key as well?
Or is that just drum editor?
This is if you only wanted the following notes selected, rather than all.
That’s right, it works in the piano roll. Double-click a note to select it and all the following notes of the same pitch.
