Help was F3-F3, but that wasn't as bad as an old DOS word processor called Samna (later became Ami Pro and now Lotus Word Pro). Help was Esc.

>The category is not "Very popular programs I disliked intensely" but if it were, WordPerfect, any version, would come to mind instantly. The hotkeys -- of course it had no mouse support back then -- drove me the most nuts. They seemed completely bizarre. Almost random, and that's no compliment. Even the most basic actions had weird hotkeys that could only be mastered by rote memorization. What was save, Shift-F7? Help was something like Shift-F3. I have mercifully forgotten the exact details but the general sense of hotkey dyslexia is accurate. (And to anyone who wants to refresh my memory -- PLEASE don't! LOL). Not being flippant here -- I seriously think its popularity stemmed in part from the unwillingness of users who had gone through the pain of memorizing weird WP keystrokes to learn a different program.

>My new Dell came with a preinstalled copy of the latest WordPerfect. You can probably guess how long it took me to uninstall it into binary oblivion, sight unseen.
