1 week no computer mouse challenge

can I survive 1 week without a computer mouse? Will a keyboard and a midi controller be enough to use my computer for doing my work, programming, documentation browsing, video watching etc...

Every year I dedicate a week or two in evaluating the tools I use.
Is there something I can optimize, something that needs refreshment?

The vim text editor / editing method is what has led me to try live without the mouse. I use it for programming, web browsing, to some extent window management since PopOs has a vim like layout.
