Comment 62 for bug 597825

f10 should act like alt, shift-f10 should act like the context-menu key, all of these should enable underlines.

if i'm in a dialog, pressing alt should turn on underlines for the dialog (e.g. the font dialog in wordpad).

there's more logic for tabbed dialogs (the options dialog in wordpad). ctrl-tab should turn them on. it's possible to turn them off.

tab in a dialog doesn't seem to turn underlines on, but if you tab to the dialog tab and use arrows to select another, it should turn them on.

it's possible to turn off underlines with some clicks, but it isn't just one, it seems to be a combination of clicks to the content area of a tab plus clicking perhaps at least to two tabs. -- i'm having a lot of trouble making them go away.

note that alt tabbing to a dialog should result in the underlines being active in the dialog.

lastly, a dialog like find (wordpad) maintains its state independently of the app window, which means i can open find using the toolbar button, then i can task switch into the dialog and in some cases i'll have underlines enabled for the dialog, but it won't influence the main window (and of course if the dialog is open and i focus the content area and press alt, then the dialog doesn't grow underlines, only the menubar).
