Would you find Humdinger's idea of having a specific key or mouse button to show the tool-tips (with no delay between pressing it and the tool-tip appearing) a major inconvenience? (This is assuming the icons are as clear as possible in their design, preferably with text captions. Otherwise the GUI could be considered broken regardless of tool-tip implementation) Here's some of the possible ways it could be implemented: - Middle mouse button acts as the "help"/"info" button when not being used for scrolling. - Alternatively (or in addition to?) a key could be used, such as one of the Windows extended keys that Humdinger suggested, or something else (e.g. right control, pause, alt gr, etc.). - It could be configured so that you have to hold the key to see the tool-tips (and rolling the mouse over different on-screen elements instantly flips between them) and releasing hides them. The tool-tips could follow the mouse pointer pixel-by-pixel in this variation, so they never hide what you're pointing to. - Or it could be configured so that the key is pressed once to show the tool-tips, and moving the mouse away (or clicking) clears the tool-tip. - Or it could even be an on/off toggle instead. Re-using scroll lock might be appropriate, since it has a (redundant) toggle operation associated with it? - Probably many other variations on the idea. Any other suggestions? Also on a related note, I'm just looking at the BeMail toolbar (which I think is a good example of a toolbar done properly), and also the Firefox toolbar. Putting the two windows side-by-side reveals that the toolbars are exactly the same height. While the Firefox toolbar is icons-only (and therefore relies on tool-tips), the BeMail toolbar manages to fit text captions into the same space, and still retains icon clarity. I mention this only because lots of people consider captions below toolbar icons to be space hogs (hence tool-tips everywhere), but that needn't be the case. If the icons are 16x16 there might be a problem, but I think having toolbar icons so small defeats the point of them anyway -- large quick-access mouse targets for the most commonly-used functions. One of the more extreme examples of that (and why tool-tips become so important when such design errors have occured): http://2.bp.blogspot.com/_9dwer2IaqWQ/SBAYc_4ws5I/AAAAAAAAALI/ bUfwrjYUhZE/s1600/msword.JPG
