Tarmak Steps

TARMAK: PAVING THE ROAD TO PERFECTION

Each of the 4 Tarmak layouts changes 3–4 new keys from the previous step until you've made the full transition to Colemak. This is done by breaking up the loop of keys that move into each others' positions, misplacing only the very infrequently used J in the process. There is one big loop of 14 changed keys (Y>O>;>P>R>S>D>G>T>F>E>K>N>J) that you can learn in up to four steps, and one small self-contained loop of 3 keys (L>U>I). Each Tarmak step brings at least one of the most common letters in English (ETAOINSHR) to the home row where it belongs, right under your fingertips.

This animated image, like the one at the top of this page, shows the full Tarmak transition from QWERTY to Colemak. The keys moved into place for each Tarmak step are shown in a different color following the rainbow from red via orange, green and blue to violet.



Here I've explained each of the Tarmak "tar lumps" in more detail:

Tarmak steps:
1) The (J)>E>K>N "most essential" loop, fixing the important E (and N)

Tarmak1(E)

2) The (J)>G>T>F loop, bringing the important T into place

Tarmak2(ET)

3) The (J)>R>S>D loop, getting RSD into place – all of which are relatively frequent!

Tarmak3(ETR)

4) The J>Y>O>;>P loop, getting O in place and finalizing the big loop

Tarmak4(ETRO)

5) The L>U>I self-contained loop - step 5 is simply Colemak!

Tarmak5 = Colemak


Here are the spectrally coded Tarmak steps again, together in one Colemak image. Not shown in this figure is how the J hops between temporary positions (QWERTY E, G and R) before finding its place; that's explained above.


The next image shows the Tarmak steps leading to the Colemak-DH ergonomic variant, should you be interested. I like it!

This image shows Tarmak-DH on an ANSI Angle(Z) modded board, leading to Colemak-DH.
On an ISO keyboard you can use a simpler Angle mod without splitting the ZXC keys.)



TARMAK-DH: STEP & CURL


The Colemak-DH alias Curl(DH) ergo mod is an ingenious way of getting the frequent D and H keys to better positions for people who dislike the "middle trench" positions (QWERTY GH) and feel that this part of the home row doesn't feel quite like home after all! See the Ergonomy page or stevep99's DH-mod pages for more info.

Keep your hands at home position (QWERTY ASDF JKL;) and stretch inwards then down. Which is more comfortable?

The Curl(DH) mod requires an Angle mod (see above) to work well on standard row-staggered keyboards. Colemak-DH is good on matrix boards too, though.

In Oct 2020, stevep99, myself and others agreed on promoting one common Colemak-DH:

Here are the Tarmak steps for Colemak-DH, shown on an ISO keyboard:

Tarmak-CurlAngle-ISO:
1a) The E>K>N>(J) "most essential" loop, fixing the important E (and N)

Tarmak1(E) "vanilla"

1b) The H>M Curl(H) swap, by default combined with step 1a

Tarmak1(E)-Curl

2a) The Angle (B>C>X>Z>_) mod, in preparation for Tarmak2-CurlAngle

Tarmak1(E)-CurlAngle

2b) The (J)>B>T>F loop, bringing the important T into place – with the DH mod

Tarmak2(ET)-CurlAngle

3) The (J)>R>S>D loop, getting RSD into place – all of which are relatively frequent!

Tarmak3(ETR)-CurlAngle

4) The J>Y>O>;>P loop, getting O in place and finalizing the big loop

Tarmak4(ETRO)-CurlAngle

5) The L>U>I self-contained loop - step 5 is simply the full Colemak-DH!

Colemak-DH

I've split steps 1 and 2 above for clarity. But if you're the careful type you may choose to split them in practice too:

The full Tarmak1-Curl(H) step is a 6-key one which may be a bit much if you're new to layout switches. If that is the case, consider taking on the normal Tarmak1 step first!. In fact, you could do the H-M swap whenever you like in the progression, but for my own sanity's sake I've put it in step 1.

Similarly, if it seems that a lot is happening in the Tarmak2-Curl(DH) step then you may try tackling only the CurlAngle mod (_ZXCVB→XCB_V in this case) first. In this case, the B gets temporarily misplaced. Several implementations allow you to select the DH mod separately.


Tarmak-DH on ANSI keyboards:

For ANSI/US keyboards, you have to choose an ANSI-Angle mod as these boards don't have the extra key between Z and LShift. The most common one is Angle(Z), which moves Z into the middle where the B used to be as XC move to the left. The Curl mod then arranges B and D as usual:
