Key questions

hi - new install windows desktop - is there a reason the home/end keys do not work in the note list? they literally have no function at all - ctrl-home seems to work but that is non-standard. is there a way to re-assign those keys to work like other apps?
Also the menu bar is hard to navigate by keyboard - Alt-T brings up the tools menu but then the left and right arrow keys do not work to move to the other menus.
Can someone also tell me the easiest way to move between the 3 panes (list, note and title)?
thanks!
