I had a hard time deciding if the title should be "programming with a mouse considered harmful" or "real programmers don't use a mouse"; but I think you get the idea
I'm mentoring a guy right now, and he started using the mouse to move around in the code, I told him
"don't use the mouse, that's a bad practice"
It doesn't matter how many years you have been programming, if you use the mouse, you are implicitly slow, you can do things at least twice as fast using only the keyboard.
leave the mouse for things that you don't usually do, but for everything that you are doing in code there absolutely no reason to use the mouse; if you are new to programming it should be a lot easier to learn to use all the shortcuts, if you have been programming for a while is definitely harder (and you probably think you're better off without them at this point) but you would definitely increase your programming speed
I am known for being pretty fast (and they say I'm cocky for that matter), but one of the main reasons I'm fast is because I learn to use the shortcuts, I had a hard time switching from Delphi IDE to VS, but I did it without remapping the keyboard to use "Delphi IDE style", I think it's a bad idea to remap the keyboard to your specific style, specially is you do some type of pair programming (you are doing paired programming, right?)
you don't have to learn all of the shortcuts available, just the ones for all the little tasks that you do commonly when programming
use the keyboard, program faster
