i am thinking of using the popular tiny mce wysiwyg editor to edit my websites on the go - ive just tried it out on my n900 and realise theres 2 things i can't work out how to to do.

right click something in the editor
drag the bottom right corner to make the editor wider/taller

can anyone work those out for me?

would another browser for the n900 be able to do these?
