As a backup I got the Varmilo VA88M keyboard. It has it’s quirks but very solid standard keyboard.

Swap CTRL and CAPSLOCK

VA68 VA87 or VA108 hold down Fn+Win key for 3 seconds to Swap.

Key commands

From VB87 Manual bot works for VA88M also:

• Fn + Ctrl (Right) = Application Key
• Fn + UP ARROW = Keyboard backlight brighter, pulses faster
• Fn + DOWN ARROW = Keyboard backlight dimmer, pulses slower
• FN + RIGHT ARROW = Disconnect current device and enter pairing mode
• Fn + Win = Win key lock
• Fn + Win, hold for 3 seconds = Swap left Win with Fn
• Fn + Ctrl (left), hold for 3 seconds = Swap the left Ctrl key and Caps Lock Fn + Esc, hold for 4 seconds = Reset to default
