I love the tips you've been sending out recently! I don't know if you have a whole bunch lined up, but some tips I give people that aren't in the tip of the day:
Ctrl-m to clear direct formatting.
You can add shortcuts to add a new row in writer, which is useful if you work with a lot of documents with tables.
If you enter certain characters a lot but don't want to remember the Unicode code point and press alt-x you can add an entry to autotext and create your own code. E.g. I use "->" and then F3 to enter an arrow to the right.
