Although shortcut keys, may be important to you, and I understand, as I used them with early editors also, but the moment we were using mouse and menus, except for Cntrl-c or Cntrl-v, I’ve completely given up using keyboard shortcuts, period. I even used to buy the 116-key keyboards to record shortcuts of only a few important keyboard keymaps/macros, but since the advent of right clicking and context senstive choices, I’ve found little use to remember convoluted keyboard shortcuts.
I even remember buying those commercial keyboard shortcut templates that fit over the keyboards to use common keyboard shortcuts…but those days are long gone for me and I suspect most users, however, as it is a mostly arcane use these days, someone really needing it is going to find it or ask about it, so I don’t think it’s hidden as much as it is “not emphasized”. But as Peter points out, it’s almost impossible to get people who use free software to read the free documentation. It’s easier for them to waste someone else’s time coming up with an answer they won’t research on their own. It’s just the times and generation we live in now, apparently. ::shrug::
