Hi,

I need the second way - break the tag I am adding.
I need to change font size of the selection. Using 
execCommand(fontsize,..) gives size atrribute, I need to use px, pt, 
etc.... But it is morte abstact - for enclosing selection with any tag.
Maybe I could use execCommand(fontsize,..), which puts tags to proper 
places and then go through all added tags (but how to know them?) and 
change them or go through all <font> tags in selection (how to get all 
nodes completely included in selection?)
It is not very clean, any better idea?

Many thanks,
Tomas
