A question about adding keyboard shortcuts in mate

[Linux for blind general discussion]

There is no need to browse applications when adding a keyboard shortcut 
in MATE. Just fill in the name and the command as you have done for 
ocrdesktop, then click the Apply button. Your custom shortcut then shows 
up at the bottom under a grouping called custom, where you can bind the 
key just as you would for any of the previously existing shortcuts. You 
can add as many ocrdesktop or any other commands as you like in this 
way, then you bind them to their keys all at once from the bottom of the 
list of shortcuts. Note that this method does not allow piping or any 
form of complex scripting, but for just running ocrdesktop with various 
flags as you're trying to do, it's perfect. Hope this helps.
