If you're using Pages, you can use Cmd-C to copy, Cmd-A to select all, Cmd-V to paste. You can also use the Shift+arrow key to select as much as you want from a paragraph.
Some of that also works in Mail as well. Using Cmd-Shift-D to send a Mail (what you can do on the desktop version) does not work. And keyboard shortcuts to select a location in Safari don't work either.
It's very irritating that the Bold, Italics and Underline shortcuts don't work with the bluetooth keyboard for ipad (they work fine if you use the bluetooth keyboard with a laptop).
The same problem occurs in Documents To Go AND with Pages. I feel like I wasted money on Pages, only buying it hoping it would not have this very basic issue.
It's so easy to resolve:
CMD-B for Bold
CMD-I for Italics
CMD-U for Underline
and CMD-[ for font smaller
CMD-] for font bigger.
It would make a world of difference if this could be fixed!
