My custom Keyboard. Colemak Modified

Motivation

I type everyday of the week. It make sense, removing hy will for complacency, that i switchh to a more efficent keyboard, if there is one. I present to you, Colemak Programming keyboard

Why Colemak

I was learning colemak and was I little obsessed with efficient workflows I started experiment. But through my experiment i found someone who had experimented with colemak keybord for years and have settle on an improved layout, so i decided to adopt the layout. Linked down below.

Current Layout

• Fingers rest on the higlight
• Wide Angle Mod: Right hand has shifted one column. Benefits:
  • Lest stress on right wrist
  • Layout is now symetrical
  • Shift R + Level5 is easier to reach:
• 8 layer layout requires 3 modifiers:
  1. Shift
  2. Level3 usually known as Altgr
  3. Level5

include "level3(lalt_switch)" // Left Alt
include "level5(ralt_switch)" // Right Alt

• Level5 is very obsure and extremely usefull to know about, if you wish to expand. It would allow for around 200 extra characters to be added.

How 8 Layers works

Layer:

1. No Modifiers
2. Shift.
3. Level3
4. Level3 + Shift
5. Level5
6. Level5 + Shift
7. Level5 + Level3
8. Level5 + Level3 + Shift

How do you Type

Numbers

• Accessed solely on Layer3
• A programmer who uses numbers often is a bad programmer see https://en.wikipedia.org/wiki/Magic_number_%28programming%29A
  • This was why it was taken off the Level1 (No modifiers)
  • For convenience, it is arranged in a number pad.
  • 1230, constitude the most common numbers and hence are found on the home row.
  • The right hand number pad has close access to -+.,#%$*/\;:= , the most relevant mathematical operators.

Alternative Characters (Requires Modifiers)

The least common alternative characters were delegated to Level3 and Level5 modifiers. They were mapped with the followind reasoning.

• @ resembles Q
• & resembles B
• $ resembles Z
• × resembles X
• ~ resembles W
• ` is on C, "aCute"
• | is on V, "Vertical pipe"
• % is on M, "Modulus"

• is on H, "Hash"

• < and > Easy Access for writing html etc.
• ^ is next to < and >
• • and - is next to the Numbers, with - easiest to access

Alternative characters (No Modifiers required)

Generally the most common programming characters that you will type exist here:

• ? ! in the corner, because they typically close off sentences. Colemak was designed that letters that end sentences are more common on index and middle fingers, and placing it here on the pinky improves hand movement. ! also remains on its original position.
• [ and ] are easy access, because Regular Expressions tend to use them a lot. They mirror ) (.
• ) ( are reversed because it is easier to roll the fingers from the pinky to the index finger. The following trigram is also very common: (); and works best in this orientation.
• " is on an easy access area, and mirrors '.
• ' is on the opposite hand as s which is important for the 's bigram.
• { } are usually automatically handled by editors, so they are placed in the hardest to reach region.
• * and / are for the /* bigram and are common vim commands.
• \ is on the right hand at the far corner, to resemble Escape and to work best with the following bigrams, \t \n \r
• ; : = are all similar, and resemble Return. Again, because they exist near the corners, and they typically end sentences, they work best on the Pinky and Ring Fingers.
• Prior Next aka Page Up Page Down are directional keys in the middle. This is exceptionally useful on Thinkpad Keyboards, as they are right next to the Trackpoint. Even without the trackpoint, it is nice when it comes to just scrolling through documents. The reason why they are not the same as Page Up Page Down is to grant more flexibility for run configurations.
• _ the underscore here works well for writing object names, and works well with the m_ and s_ bigrams. It also is not a letter because that makes shifting it a painful exercise.

Directional Keys

• Inspired by Vim.
• Without the Wide angle Mod, the thumb will cramp up reaching for level5
• Amazing for editing regular documents.

Letters

Shift + [A-Z]

• Capslock and Enter Removed and replaced by Shift
• Shift's are replaced by Control
• Shift's are 3× more comfortable
• Control's are 5× more comfortable
• Capslock was not missed. Prefer it as Shift over Backspace or Escape provided that I have access to those keys on Level3 or Level5

Return

• Placed on the o because in vim, its functionality is similar to Enter.
• Surprisingly, not a big issue. I would consider it maybe 1.3× more difficult to use compared to its original position, which is great tradeoff to be able to get Shift on the home row.

Functional Keys

Accessible by either modifier.

• Backspace is on the left pinky, to be intuitive with the direction you are deleting.

• Delete is on D, and is intuitive with the direction you are deleting.

• Escape for some reason, feels best on the Ring Finger, rather than the pinky.

• End and Home are inspired by a colemak Vim configuration:

• InSert, which will go to the beginning of the line before editting. Append being on the T, which goes the opposite direction. Backspace is used 10× more ( Meaning that I will use the Home Row position 10× more, rather than its default position. ).

• Delete is used about 20× more.

• Escape is used about 15× more.

• Home and End is used about 200× more often and utilized far more often, being especially useful in editting documents outside a vim environment.
