Raise Sexp/Form needs updated doc and shortcut keys

[bpringe]

Raise Sexp/Form, according to the docs, is mapped ctrl+alt+r, but in the editor with the latest Calva it is mapped to ctrl+alt+p, ctrl+alt+r <-- and this shortcut doesn't work because another command is already mapped to ctrl+alt+p so that command takes the shortcut before the next chord can be entered.

So I think this command needs to be remapped, but I don't know that ctrl+alt+r will work for the same reason noted above with ctrl+alt+p. Other commands have ctrl+alt+r as their first key chord.

The name of the command in the docs can have "Current" removed from it, and there are a few others that could have "Current" removed from the name in the docs too. I think it was removed from the command names in the code/editor.

Another thing I noticed which is a quick-fix so I'll just include it here: the Transpose Sexps/Forms command has ctrl+alt+r in the docs but it should be ctrl+alt+t.
