Ah, sorry I missed that! I was looking for something more than one line.
I got ctrl-alt-s to work in metapad, my text editor. At first it didn't work, then I first Selected the text and it worked, and thereafter I didn't even have to Select the text first and it worked.
I couldn't get it to work in Slimjet (Chromium) or IE10, even with selecting the text. I'm on Win7 x32. It says Spellcheck Completed, but does nothing.
What started me on this quest was a program I use a lot that doesn't have spell check. I got TinySpell Free and it works quite well (except the popup is way out of place in Slimjet). I began to see the benefits of having a system-wide spell check - it would hit every program, and there would be only one dictionary to maintain. TinySpell has a nice feature where you can set it to either generally off or generally on for applications, and then make exceptions. It also does live spellcheck, which is great, but it doesn't correspond with MS Office dictionaries as CHS does (very nice).
And so I'm considering getting the Pro version of TinySpell, but would rather use what I already have first if possible.
