Keyboard shortcuts between Mac and PC

Hi, I work on PC at work and Mac at home, I'm constantly battling with
having the shortcut key differences between mac and PC, the biggest
problems I'm having are:

Insertion Point to Previous|Next Word
- PC: CTRL+<LEFT|RIGHT>
- MAC: ALT+<LEFT|RIGHT>

Fix Imports
- MAC: APPLE+SHIFT+I
- PC: CTRL+SHIFT+I

The other one that's driving me insane is probably a Mac thing that I
don't know how to change
- MAC: HOME|END - Move to start/end of document
- PC: HOME|END - Move to start/end of line

How do you even move to the start/end of a line on a mac?

If anyone knows a workaround to this please let me know, even if you
have a set of recommended key mappings will do for me.
