The drawbacks to single click (well spoken tut btw)
1-lag before file or folder is opened (increase double click speed to help, but good luck performing a double click in an actual application.)
2-Things get selected accidentally, especially when making ctrl+clicks (imo, holding the ctrl key should automatically switch things over to single click mode.)
2.1-With the Save as dialog box, files can sometimes get clicked and you have to manually rename the file to it's default name.
3-Renaming files and folders is less convienient (F2 if your hand is near by)
4-Setting focus to a file in a window that is not active requires a middle click and a hover. (I usually end up left clicking the title bar instead of mid-click cause that button is easier.)
5-Waiting for the mouse hover is SOOO boring. (edit: just found
Mouse Hover Time - Change)
I haven't switched back cause of hand problems but I have concidered hotkeying a toggle between single and double mode (I do batches of task 2, 3, 4 and 5 periodically). Does anyone know how to set up that hotkey by any chance?
