Many of the layouts developed by trialyzer are rather strange. However, now and then a few of them look like they might actually be good. I may also end up making layouts by other means, and those will be included here as well if I deem them sufficiently noteworthy.

These layouts may be subject to change; any changes will be indicated if they occur.

This layout is for the brave. Due to the right index being completely packed with moderately-common consonants, it is probably better to use this with a column-staggered board (f in is in a bad spot for row stagger).

Features:

• Low sfb, extremely low dsfb
• High rolls, frequent onehands such as ion, one, are, ine
• Reasonable redirect level, though beware of no-index redirects such as rea/ear and (less frequent, but worse) ean/nea.
• Some weird scissory movements such as 'r, wh, and your typical or/an half-scissors with this kind of rn/oa interaction.
• Vaguely low-ish lateral stretching
• Busy pinkies

Tips:

• Using a repeat key would be helpful to remove ee double-taps on the pinky.
• Applying angle mod is... not great, not terrible.
• If a 2-row change between the middle and index finger (like ai, ly) is not good for you, you will probably want to rearrange the indexes. Good luck.
• Swapping f with v gives you the original enou. This increases pinky load, and makes it even harder to type sfb if you are someone who talks about keyboard layouts a lot. However, in return you get the lowest genkey-weighted dsfb count ever seen, and a slightly less common letter in that top index corner.

This layout is designed for a row-staggered board with angle mod. Preferably, the right thumb should press space.

Notable characteristics:

• High rolls, majority inward.
• Unusually high onehands, extremely inward (2.4 inward ratio, increases to 3.3 when adding space on the right thumb).
• High redirects, though only slightly higher than Colemak.
• Low alternation.
• Low lateral stretching and reasonably low dsfb.
• Index finger keys can optionally support alt fingering and/or sliding to remove same finger sequences, such as rm, wl, sys, cyc, gs, sc.

This layout is tricky to obtain in a non-angle-modded format. (Cycling z to the left end of the bottom row causes w to get a bad position, so you have to either rearrange more keys, or just cope.)

This layout is a mod of the rolll layout by Semi, and was developed in collaboration with <3 and trialyzer. It introduces angle mod and reduces same-finger and lateral-stretch frequency compared to the original rolll layout.

Rollla is designed for a row-staggered board with angle mod. Preferably, the right thumb should be used for space. Notable characteristics:

• Low dsfb (better than vanilla semimak) and fairly low sfb. Low lateral stretching.
• Plenty of rolls, especially inward rolls.
• Very reasonable redirect frequency considering the level of rolls and onehands.
• Moderate alternation.
• T on the pinky may be intimidatingly high frequency, but the movement on that pinky is actually very low.

A variant of rollla (see above) but with the / replaced by a repeat key - this is indicated by the position marked R, and is pressed with the left thumb. A repeat key simply duplicates the previous letter, which essentially eliminates double-tapping, thereby reducing finger movement and strain. Since double letters make up about 2.5% of bigrams, this may be a significant gain. Trialyzer data shows that double letters are nearly as slow as sfbs.

This is the layout I currently use. The layout is called rolllax because the repeat key is on what would be x in QWERTY. Pressing it with the left thumb may sound extreme, but seems to actually work quite well.

Genkey does not support repeat keys and also does not support thumb keys. Therefore, in place of the genkey stats, below are some statistics (edited for brevity) from my copy of trialyzer, including (weighted) typing speed data. This shows the difference in stats when moving from rollla to rolllax. Note that the sfr category has been completely wiped out by the repeat key, resulting in a substantial stats improvement.

This layout is designed for a row-staggered board with angle mod. Preferably, the right thumb should press space.

Notable characteristics:

• Incredibly frequent onehands, including the most common trigrams such as the, and, ing, ion
• Rolls tend to be leftward, interestingly.
• Low sfb, dsfb, and lateral stretching.
• Redirect levels comparable to Colemak.
• Low alternation.
• Based on a test drive, the main problem points are on the left hand: imagine typing useful, or lemurs.

For a non-angle-modded version, try cycling z to the bottom left. You may want to also swap w with k, and y with ', to get those more common letters out of the corners, especially for non-row-staggered boards.

2023-03-17: Swapped q and z between hands to improve qu and slightly lower same-finger stats. Cycled punctuation to improve '. Previous version:

These layouts are a lot like seht-drai, but with m and f moved to fix some awkward redirects and scissoring movements on the left hand. seht-frai has a yi pinky. seht-yfrai moves y to the index finger, reducing pinky load but adding a smidge more LSB. Both layouts lose the and onehand, and have slightly more LSB than seht-drai.

These layouts are designed without angle mod. Applying angle mod doesn't add a huge amount of extra sfb to the left index, but it does add yet more load to that finger, which is already the busiest finger. Genkey suggests swapping m and k to reduce movement.
