What is this Tarmak-dh

Tarmak-dh is a way to learn the Colemak-DH(m) keyboard layout in steps which make the transition easier. Colemak-dh(m) is a variation of the classic Colemak keyboard layout which moves the D & H keys to better positions Explanation by stevep99 Explanation by Dreymar. The Colemak-DH(m) standard ergo mod is a variant upon Colemak-dh which was agreed upon to be jointly promoted by the community as it works well for row staggered and matrix keyboards.

Specific keyboard layout being used

Instructions

Based on whether you have an ANSI keyboard (there is no key between shift and your z key) or ISO keyboard (there is a key between shift and your z key), go the either ANSI or ISO folders to find the keyboard layouts that you need.

This is the tarmak 1a keyboard layout shown above.

ANSI has the angle z mod while ISO is just the layout by DreymaR

Installation

Put the bundle you need into either directories:

/Library/Keyboard Layouts aka Macintosh HD > Library > Keyboard Layouts if you want to install system-wide for all users (recommended). It should ask for your password to move it.
~/Library/Keyboard Layouts aka Macintosh HD > Users > USERNAME > Library > Keyboard Layouts if you want to install for only yourself, so the keyboards won't be used for sensitive inputs like password entry.

Go to system preferences, keyboard > input sources and use the + button in the bottom left corner to add the keyboards listed below:

TarmakDH 1a.keylayout
TarmakDH 1b.keylayout
TarmakDH 2a.keylayout
TarmakDH 2b.keylayout
TarmakDH 3.keylayout
TarmakDH 4.keylayout
Colemak DH ANSI.keylayout

You can select multiple to add at once.

Usage

Order of progression - I think you can skip past (a) to (b) layouts if you want

TarmakDH 1a.keylayout
TarmakDH 1b.keylayout
TarmakDH 2a.keylayout
TarmakDH 2b.keylayout
TarmakDH 3.keylayout
TarmakDH 4.keylayout
Colemak DH ANSI.keylayout

Also if you are on a mac, you can actually turn on the keyboard viewer in keyboard preferences so you have the keyboard up for reference.

Additionally I have wallpapers you can use for each keyboard in the Wallpaper folder, you can make your own with the images in the Wallpaper/DIY folder or go to the top right corner (...), Customise "..." and add your own panes (I color each change to make it easier to find the swapped keys)

End keyboard

You should end with Colemak DH + Z angle mod. This is the same as https://github.com/ColemakMods/mod-dh/tree/master/macOS

Useful

Fingering

Images from DreymaR

Your fingers should be on the home row:

You should press each key based on the color it corresponds to:

Custom Text

if you use https://www.keybr.com/, you can go to settings, advanced from the practice page in order to add your own custom text. I am essentially trying to reduce use of keys which are going to change.

I made my own using an unscrambler and randomly shuffling words. You can use those in [Custom Text folder](/Custom Text)

Still would recommend going to https://monkeytype.com/ to write out actual passages of word which you will use while transitioning.

Considerations

Letters that always stay the same:

Q, W, A, U, I, L, V, , . / [ ] ' \

I don't usually include punctuation in my training, though I might for the last one which changes semicolon position.

For each stage of TarmakDH mod (ANSI)

Which letters after this change will be in same position as final layout.

Tarmak-DH (ANSI) (1a): N, E, K

So should train on words with Q, W, A, U, I, L, V, N, E, K

QWAULIVNEK

Tarmak-DH (ANSI) (1b): M, H

So should train on words with Q, W, A, U, I, L, V, N, E, K, M, H

QWAULIVNEKMH

Tarmak-DH (ANSI) (2a): X, C, Z,

This is with z mod, so ZXCB change places but only XCZ are in final positions

So should train on words with Q, W, A, U, I, L, V, N, E, K, M, H, X, C, Z

QWAULIVNEKMHXCZ

Due to 12 character limit of unscramble, I essentially did 2 scrambles of

WAULINEMHXCZ
QAUIVNEKHXCZ

Removed by lowest letter frequency:

Q, V, K,
W, M, L

Tarmak-DH (ANSI) (2b): F, B, T

So should train on words with Q, W, A, U, I, L, V, N, E, K, M, H, X, C, Z, F, B, T

QWAULIVNEKMHXCZFBT

Tarmak-DH (ANSI) (3): R, S, D

So should train on words with Q, W, A, U, I, L, V, N, E, K, M, H, X, C, Z, F, B, T, R, S, D

QWAULIVNEKMHXCZFBTRSD

Tarmak-DH (ANSI) (4): P, J, Y, O, ;

So should train on words with Q, W, A, U, I, L, V, N, E, K, M, H, X, C, Z, F, B, T, R, S, D, P, J, Y, O, ;

QWAULIVNEKMHXCZFBTRSDPJYO;

Colemak-DHm (ANSI) z-mod: L, U, I

Basically should just train on full text but might want to do ; coz it has moved along with : (shift ;)
