Windows access keys do not work in Rhino 8

Windows access keys which allow selecting options with one key from right click or other context menus are not working in Rhino 8 SR2 (822346.13001, 12-12). Options from the very top bar (e.g. File, Edit, View, etc…) do work as expected, but Grasshopper and any toolbar within a container do not seem to work.

Example: Previously in Rhino 6/7 you would be able to collapse all sublayers by right-clicking and then hitting “C” on the keyboard. After the right click on Rhino 8, the keyboard entry will start typing in the command line. These windows shortcuts can typically be viewed by holding down the alt key when opening a context menu.

This seems to be related to the issues seen with the flatten and graft shortcuts within Grasshopper mentioned here: RH8: Tree shortcuts are not working


Hi Paul - I see this thanks.

RH-79560 is fixed in Rhino 8 Service Release 4 Release Candidate

Is this still the case? Seems like that ticket was punted forward to a future release.

Hi Paul -

For some reason, those “fixed” messages are sent out when the issue goes to “Needs Testing”. When the tester then decides the issue is not fixed, it is reopened.

When a public build is released between the point where the issue goes to “Needs Testing” and actually gets tested, the “fixed” message might be premature.

We want everyone to test fixes, not just our internal tester. So we don’t require our testing staff to agree that it’s done before we announce it. This gives us faster feedback from customers.

I don’t know what to say. There is something sluggish and half functional about this whole R8 UI.

Hi @anon,

This is on the list.

Agree with you the whole RH8 UI is laggy and lost lots of efficiency in the workflow(in GH as well). How long could it take to have those issues fixed? Just got Rhino 8, but I can’t use it in its current state.
( Can it be linked to the Mac and Win UI coinciding? key acces in menus doens’t work on Mac os, if i remember well )

hi @q.andreotti General statements won’t give us any info on what works and what doesn’t for you. It will be helpfull if you you list the issues you are facing, so they can be logged and addressed, thanks!

You’re right, here are my problems so far :

  • lag/freez for a 1sec when expanding / collapsing layers
  • cannot use key commands on menus / contexts menus in rhino + grasshopper.
  • sellayer doesn’t work if the targeted layer is in a collapsed layer folder.

Version 8 SR2
(8.2.23346.13001, 2023-12-12)

That YT is for layer panel drag to select. In addition, my video gif demonstrates the OP’s bug, failing Windows shortcut keys, in my case E and C for expand and collapse, within the layer panels.
