Thanks!

There were quite a few changes to the Horde::addParameter in the meantime since 
I sent the patch and you committed it, so I have a new patch that merges the 
other changes as well.  I also added the code to a couple other pages; also 
incorporating the intervening addParameter changes.  A couple people responded 
off-list that they would prefer this to be a per-user preference, so I added 
that as well...

The patch is at http://www.wild-e.com/horde_patches/widget_accesskeys.diff

I'll keep it up to date with changes that I see that may supersede it in the 
meantime.

Also, the recent change to Horde::includeScriptFiles is troublesome to me if I 
have compress pages set to true.  It appears as though, in this case taking 
mailbox.php for example, IMP::composeLink is called after 
Horde::includeScriptFiles is called, but headers_sent() returns false, since 
the 
output is in the buffer awaiting compression.  Setting compress pages to false 
makes it work correctly again.  This is with PHP4.3.1-cvs; possibly a PHP issue?

Thanks
