Tools-Quick Select... lets you pinpoint exactly what you want to select in the drawing (i.e. all of the text, all of one layer, etc.)
Modify-3D Operation-Align... I use it more in 2D... and it is AWSOME for making one object the same angle as another...
Edit-Copy with Base Point... was mentioned in other threads, but I thought I'd emphasize how great this is... lets you copy something with a point of reference (as the name states!)
Also... I have several buttons created for these, as well as REGEN, UCS Icon On/Off, and my own custom Close button.... I'm a little faster at clicking than typing..
See Attached.... and Enjoy!
