I’m using this keyboard with a Linux computer over USB. There are some pain points using this keyboard, like needing to hold the “Fn” key to use the F1-F12 keys (and even Esc!), and that the “lock” button (right next to the backspace and delete keys) sends a XF86Power command that shuts down the computer if you accidentally press it.
The main issue I’m having is that some key combinations don’t seem to work correctly. For example, if I use Ctrl+Tab I can cycle through tabs in the web browser. But if I use Ctrl+Shift+Tab to cycle backwards, it doesn’t work. If I use a tool like xev to see the inputs from the keyboard, if I hold the Ctrl+Shift keys and then press Tab, it shows that I released the Shift key even though I’m still holding it down. The same thing happens if I try to Shift+PageUp. If I hold Fn+Shift and press the Up key, it shows a “KeyRelease” event for the shift key even though I’m still holding it down.
Is there an issue with my keyboard, or is it just wired in a way that doesn’t allow these key combinations? The Shift key works fine in other uses, for example holding Shift while pressing arrow keys to select text.
