Key command + feature requests

Begging you for a couple of things. I'm a patient man, so whenever you get to it, pretty please.....
Simple, one press key commands for:
1. Create a dal segno
2. Create a coda
3. Create left and right side repeats
4. Create repeat text
5. Reverse the order of note entry - rhythm the pitch, pitch then rhythm.
You get the idea....
Also great would be a command to put everything selected on one page and lock it (arguably the best feature of Sibelius, which is in many OTHER ways inferior to MS in my opinion) - having the program automatically resize staves, notes, whatever is necessary. So far in every part I've written I get my pages all nice and neat with rehearsal letters at the top of each one, then I add one small thing (a repeat sign or system text) and it pushes one staff over to the next page, requiring futzing around....
Great program overall guys! Do you accept donations? I can't believe it's free....
