Deleting marked word

[Martin]

Hi,

today I wanted to replace a word by another. OK, I should do it with 
replace, but it was only one word! The strange thing was: I marked a word 
by double-clicking. And then I didn't find a way to delete the word. 
Whatever I did, Backspace or Delete, it was just Cut. Why? Is there a 
sense? Sorry to say it, but in Word you can copy a word and then you can 
replace another by marking it with double-click and then do a Copy. I 
think this is very useful, isn't it?
I'm using 1.1.2.
Thanks,
        Martin
