Add direct keyboard shortcuts to apply text styles

Very sorry for answering so late, I hadn't discovered your answer above.

RTF export: You're right, multiple selection will do it! (I had, in vain, assumed that parent item plus its child items would be processed, but multiple selection will provide much more precise selecting, so in some cases, it's a little bit cumbersome, but overall, it's the better solution indeed (in the absence of more fine-tuned options being available).)

As for XML export, I'll create another thread.
