[*Results may vary. Contains no traces of peanuts.] No matter what kind of web work you do there is a small quiver of keyboard shortcuts you should memorize. Shortcuts you’ll want to use over and over and over again. Think about it … in a single day a typical computer worker will run the same commands repeatedly; stuff like “Save” , “Undo” … right? Go with me here for a minute while we run some conservative numbers. OK, let’s assume it takes an average of 3 seconds to go mousing for menu commands that you use an average of 10 times an hour (3 seconds x 10 repetitions an hour = 30 seconds per hour). Then times that by a 8 hour work day (30 seconds x 8 hours = 240 seconds) and you get 4 minutes for the day.
Before you start thinking woopdey freakin’ doo … go ahead and multiply that 4 minutes a day by the 250 odd work days in any given year and you get: 1,000 minutes. Now replace those mouse actions with much faster keyboard shortcuts — which I estimate are at least two thirds faster — and you’re on your way to an extra 660 extra minutes (11 plus hours) in your life per year to spend doing something else than mousing for File > Save.
