I did think about this topic many times. My conclusion: We need some other kind of interface (keyboard and mouse at the same time which would speed up your workflow very often, especially when doing some kind of graphics where you have to enter some text).. One solution I did find is http://www.combimouse.com/index.htm .. But I have'nt been able to afford this nice idea to test it. Another is one is http://www.jazzmutant.com/lemur_overview.php (too expensive to be buyed by me in the near future .. ) Another example is the iPod ... stop << >> move the finger to on the surface to scroll play (or something like this), I don't have one. I totally agree that you can't say the one is faster than the other way. When I'm faster using the keyboard (Perhaps I only think I am? :) finding logout (find as you type firefox), because I can even reach the link if it's not in the visible area. Finding directories I use often (because I don't have to look at many files/ directories I'm not interested in.. Perhaps my visual perception is not as fast as the perception of others?) Compare using property editors with code (find property visibility in either alphabetical or sectioned).. Finding menus on Windows (Because the move very often if you install new software, work on foreign computers etc).. But that's why tools like lounchy (windows) exist. Moving Windows using wmii (althoug nifty windows for Win is very nice as well, but you have to take off your hands..) scrolling (using page down/ space / return application dependend) tying gimp<tab> instead of (where the hell is that icon? Oh no it looks different because I have a newer version ..) using special commands such as goto previous cursor position... Opening files using glob patterns in vim (having mapped **/* (eg :e **/*some.hs<tab><cr> ) Opening most recent files having them listed in a buffer where I can use search. (compare this to File -> Open -> c:\MyProjects\..... ) I'm faster using the mouse: navigating in directories I don't know.. (But often I use something like find | less to get an overview ) ... My friend is using the mouse most often. He is very fast. But Sometimes you can't get as fast as using the keyboard because you have to wait till the application pops up the window so that you "see" where to click. (Example: A lot of windows Dialogs (Eg change the PATH variable)) Anyway it would be really interesting to use 2 mice for some tasks. Then you can use one for scrolling and the other to click and drag. Or you can put both on menu items (where you think they'll pop up such as File -> save) and click in sequence. But this havily depends on the application. Eg MS office (Not the new redisigned gui) is horrible because it does always hide the menu items I'm looking for (perhaps because I'm not using them very often or I don't know yet how to switch them off). Another horrible examples are tex editors wether you can click on buttons inserting \alpha \beta etc. Then you are switching between keyboard and mouse all the time. If the mouse is faster why does eclipse have so much opportunities to filter lists/ trees ? But I do know that I really like tools such as xfig / inckscape because they have the keyboard shortcuts I need (select tools/ view ..) And you are definitely faster using them using the mouse to select the tool and moving back. But of course you have to learn them. When watching my sister or my father using the mouse very often they simply click on the small triangle (step up / down) in scrollbars instead of PageUp/Down. But this is a kind of usage pattern which can be <========================[ ] ====> step page left move .... left improved by using scrolling (middle mouse button click), maximizing the window (Windows often doesn't permit this, eg when customizing menus or shortcuts (Visual Studio/ Word etc) before scrolling down a list etc.. I hope I didn't talk too much and that you have found some stuff in this post you didn't know already ... Marc PS: How would mouse gestures compare to keyboard shortcuts concerning the 2 seconds amnesia having been mentioned in article some posts ago?
