I used to experience the same problem.
It was always so annoying having to press "Shift + E, and then move the middle middle finger on my left hand to press the "1" and "2" keys to open the various doors.
This was causing so much alarm and discomfort that a visit to the Doctor confirmed that the complaint was identified as "Middle Finger Pressing Keys "1" and "2" Syndrome".
To prevent a re-occurrence I have now learned to stare at the Monitor, concentrating very hard on the doors, and I can will them to open and close without ever touching the keyboard.*
So no more messing about, tapping keys...
