I am still a bit ambivalent on remapping keys on a keyboard, mainly because of two reasons:
- Without remapping, tools used for virtualisation, remote access and shells already get it wrong every now and then. Finding causes is already tough, so adding more degrees of freedom complicates this more.
- Switching systems or assisting people without the tools can be cumbersome. I vividly remember the really hard times when I had switched from Windows Explorer to Windows Commander (now Total Commander) and could not use it on a sequence of contracting jobs.
Just in case I am going to use it:

Cool: Magic SysRq key – Wikipedia
The magic SysRq key is a key combination understood by the Linux kernel, which allows the user to perform various low-level commands regardless of the system’s state. It is often used to recover from freezes, or to reboot a computer without corrupting the filesystem.[1] Its effect is similar to the computer’s hardware reset button (or power switch) but with many more options and much more control.
Sometimes reading fluffy fluff posts teaches you new things, so be sure to read this one:
[WayBack] I just got trolled by my cat, hard. Last night i left my linux laptop open and running while watching TV in the other room. I came back to find Marley … – Stephen Shirley – Google+
…
I started looking through the kernel logs from last night, to see if there was any indication of the issue starting. And then i saw it. One innocent line that said:
Dec 18 21:26:52 x240 kernel: [373001.156356] sysrq: SysRq : Emergency Remount R/O
The fluffy dumbass had somehow hit the Sysrq [0] key combo to mount all filesystems read-only. This is an old, low-level when-all-else-fails facility for dealing with an linux unresponsive system, and fluff-for-brains Marley had somehow hit alt+fn+s+u.
Sigh.

I always forget which colours the [WayBack] PS/2 port for keyboard and mouse have.
Some of my old (some call it classic or vintage) mice and keyboards don’t even have a coloured plug.
Luckily, Wikipedia has the answer File:Ps-2-ports.jpg – Wikipedia :
| Color |
Description |
| Purple |
Keyboard |
| Green |
Mouse |

Since:
- many people use the left-alt key as it as it is more accessible
- development tools uses a lot of Alt-Shift based keyboard shortcuts
- Windows by default has the Left Alt+Shift shortcut enabled to switch language+keyboard layout combinations
- In most countries, Windows by default has more than one language+keyboard combination installed
- Windows remembers per application instance which language+keyboard combination is used
every now and then you will get strange characters in only your development tools.
You can change this Windows setting, but be aware that every now and then, various Windows versions will re-enable the Left Alt+Shift even if you have previously disabled it. As of Windows 7 this occurs far less often, but still seems to occur.

Accessibiity -> Zoom -> enable checkbox” class=”size-medium” /> Preferences -> Accessibiity -> Zoom -> enable checkbox
I didn’t know this was built-in since Mountain Lion and up, but it is, is startable from the keyboard and it’s tremendously convenient when presenting: [WayBack]: OS X Mountain Lion: Zoom content on the screen.
TL;DR:
- System Prefrecences
- Accesibility
- Zoom
- Checkbox

If it had function keys, I might have ordered it, but in case anyone is still interested: order before the end of July as they will likely not do a re-run of this unique project: [Archive.is] Brand New Model F Keyboards – The Model M Predecessor: Mechanical Capacitive Buckling Spring Keyboards with NKRO.
Model F quality is much better than Model M, which is way better than anything manufactured after that. Just compare the spring mechanisms below.
