I’m a follower of general principle of modifying your devices so much that literally no one except youself will be able to use it.

My one-handed keyboard layouts

Since 2015 I work with solely left hand on the keyboard, while right hand controls the mouse. This comes handy in hotkey-dominated software like Photoshop or AutoCAD.

There are other known ways to type one-handed, but most of them are:

• Concentrated only on typing letters, ignoring numbers/symbols/F1..F12/etc
• Do not provide convenient way to use Alt/Ctrl/Win modifiers
• Sabotage two-handed typing speed or don’t provide two-handed mode at all
• Using special rare and expensive non-standard keyboards

For this reason I eventually developed my own one-handed layout (OPRIQ) to make it free from outlined disadvantages. This process took around 8 years.

My hand-wired keyboards

I created some custom mechanical keyboards specifically to use with OPRI and OPRIQ layouts.

All my keyboards are:

• Coded on Pro Micro controllers with QMK firmware
• Handwired
• Using random keycaps, so don’t put too much attention to keycaps captions
