Things you discover after years

A couple of weeks ago I found out you can get a little mini map on screen when you hit shift + M.

Good tip. I may use that.

Well, I haven't played for that long but have just discovered you can choose previous chat sentences by hitting enter and then pressing Alt and the up key.
Handy if you need to repeat long sentences at anytime without having a macro set up.

Have you tried Num-Lock?
If it's in the standard Key Bindings, you'll auto-walk/run ...
You can steer with your mouse and chat in the meanwhile (or do other stuff)

Also slash-forward ("/") makes you walk instead of run.
Easy with escorting NPC's
