Vertically Centering Text in Writer

Well, I think a vertically aligned text is quite rarely used (except for making signboards like "Do NOT disturb" or similar).
So, there is no shortcut. But it is not so much work:
Write your text and select it (<CTRL-A>)
1.) Insert Frame by typing
<ALT-I>M
2.) Set width automagically:
<ALT-U>
3.) Select vertical align
<ALT-V>C
4.) Select reference:
<ALT-O>
select 'entire page' or 'page text area' - as you wish
5.) confirm by pressing <ENTER>
It's eight keystrokes that can be recorded as a macro and assigned to a shortcut to your liking.
