Here’s some shortcuts I’ve been using as I transition from FCP to Premiere:

Mark Clip. By this, I assume you mean selecting the in and out of a clip. Press Shift+/

Go to In / Go to Out: q / w
Clear In / Clear Out / Clear In & Out : d /f / g

Cut all tracks (called extract in Premiere): ‘ (the key to the left of the return key)
Cut all tracks and leave a gap (lift): ; (the key to the left of the ‘ key above)

If you go to Edit > Keyboard Customizations, you can also change the keyboard shortcuts set to be like FCP or Avid so you feel more at home, if you like.
