The question is in my head & I am asking for education from my friends at DC.
Sometimes I am troubleshooting a problem & would like to restart in Safe Mode. Is it possible to add a selection to the shut-down options to "restart in safe mode?" or is it an action that happens so early in the process that it cannot be controlled until Windows is truly running? like at root level...
maybe the ability to hold at the screen where one chooses options, like safe mode or with networking...
Or is it something that only Windows developers could include in their OS?

I have used Synergy for several years. I am now running the latest Synergy Plus revision. Ordinarily I have 3 computers running, dual monitors on each, and sometimes one of my laptops. I can keep my development machine free of widgets and gadgets while running continuos weather monitor on different computer and eMail/messaging on a third. Just mousing past the screen edge of my primary machine puts me over on the eMail machine, type a quick response & mouse back to the work machine. Or set the big guy to render something & mouse over to another machine while primary is busy.
I am a fan of Synergy in all its versions & glad to see it discussed on DC, my other "gotta' have it" resource.
