Just set 10.10 up on an SSD drive plugged into USB earlier. Kudos for getting it to this stage!
Workspaces beyond 4 cannot be assigned a keyboard shortcut
Setting keyboard shortcuts to switch workspaces can be assigned for Workspaces 1 to 4 just as before via Budgie Control Center/Keyboard.
With X11 it was possible to use dconf to set shortcuts for additional workspaces (up to twelve! Six is the sweet spot for me).
Example
For Workspace 4 this is good:
org.gnome.desktop.wm.keybindings switch-to-workspace-4 ['<Primary><Alt>KP_Left']
For Workspace 5 this does nothing:
org.gnome.desktop.wm.keybindings switch-to-workspace-5 ['<Primary><Alt>KP_Begin']
This is by way of a papercut, and a workaround is to use the shortcuts for Move to Workspace Left/Right
The same limitation applies to moving windows to other workspaces---assigned shortcuts do not function beyond workspace 4.
On the other hand, it's a cause of celebration that when switching workspaces the app last focused remains focused, and the mouse button no longer has to be clicked to be able to interact with it! That behaviour was sorely missed for a long time :-)
