I’m very often use different highlight with shortcut.
I found always use 3 keys for highlight, and so long distance with left hand. , I always get tired.
I know the standard H key with index finger of right hand. but my right hand need control mouse.
Left hand with 3 finger
Little finger for Ctrl key,
Ring finger for Shift key,
index finger for H key.
X ：the distance with Ctrl and H key .
Y: the distance with Alt and H key.
Y < X.
I think that if the highlight key is Alt + H that’s less distance with only 2 keys and only left hand.
