Watched some of this great video: So how does a PS/2 keyboard interface work?

Resetting a WASD Code keyboard
I have a CODE V3 104-Key Mechanical Keyboard with Cherry MX Green switches which I love. But unfortunately it has been my experience that they can be a bit finicky. I had to return one to WASD once because keys started producing “gibberish” if pressed the keys too hard. I know! Crazy!
Anyway I had a similar problem today. My Pause key, when pressed, would simultaneous ‘mute’ my audio *and* turn it either ‘up’ or ‘down’ (with a preference for ‘up’). Friggin weird. Anyway I was able to fix the issue by doing a keyboard reset.
To do a keyboard reset: unplug the keyboard, set SW4 to the “on” position, plug it back in. Wait until the solid green lights emit and then unplug, set SW4 back to the “off” position and then plug the keyboard back in and test. Easy peasy. :)
Disabling F6 ‘Run Main Project’ hot key in NetBeans because of G15 keyboard
I have a G15 keyboard, and I love it (but not as much as the old model!), but it occasionally causes a problem for me when I’m programming in NetBeans on Debian GNU/Linux.
The issue is that on a newer G15 the G6 key is right near the Ctrl key, and from time to time my pinky hits the G6 key which seems to be by default programmed to be the F6 key.
By default in NetBeans the F6 key is the ‘Run Main Project’ hot key, so when I accidentally press it, it fires up a Firefox window and tries to run my web app! I never configure my web apps in NetBeans, but even if I did, I don’t want to accidentally run anything due to an accidental key press.
So my solution was to disable F6 in NetBeans, and for that:
Tools -> Options -> Keymap -> Click ‘Search in Shortcuts’ -> Press F6 -> Click on the ‘…’ in the Shortcut cell for ‘Run Main Project’ (should be F6) -> Clear -> Apply -> And you’re done!
Everything is easy when you know how!
Input keyboard for decimal input on iPhone
So I needed to adjust a value (the odds of a horse winning a race) that has a fractional part and an integer part (i.e. a ‘double’, or ‘float’). The standard numeric input on an iPhone doesn’t include a decimal point, so I needed to trigger a different input device.
I ended up with this:
<input type="number" pattern="[\d\.]*" step="0.01" inputmode="numeric">
WinKey+R in KDE
So I found this:
Go into “Global Keyboard Shortcuts”. Under “Run Command Interface” you’ll find ‘Run Command’. Under “KWin” you’ll find a ‘Show Desktop’ entry which is the equivalent of minimize all.
