1)When presenting a slide show in Impress, the mouse wheel enables you to move 
forward one effect at a time, but if you try bo move backwards through the 
sequence, it only enables you to move to the previous SLIDE - and not to the 
previous effect. This is a major defect when making a presentation when you 
need to go back a step.

2) In all the OpenOffice components, it is not possible to alter font size by 
using key short cuts i.e. CTRL ] to enlarge and CTRL [ to decrease, as is type 
case in MSOffice. The incorporation of this feature would make it much easier 
to adjut the size of fon to fit the space it's in exactly and quickly, rather 
than having to use trial and error in selecting a font size from a drop down 
menu.
