Everything You Need to Know About Engram
Engram is an alternative keyboard layout designed by Arno Klein using a unique optimization methodology that considers both letter frequency and the biomechanics of each finger. It places a strong emphasis on hand alternation and assigns key positions based on individual finger strength and dexterity measurements.
Best for
Best for typists who want a deeply reworked language-optimized alternative and are willing to relearn both letters and symbol logic as one system.
Main challenge
Engram's main challenge is that the punctuation and number row change as deliberately as the letters do, so the switch feels deeper than a letter-only remap.
History and Origin
Arno Klein developed the Engram layout (the name is a blend of "ergonomic" and "engram," meaning a memory trace) with a methodology that goes beyond simple letter-frequency analysis. Klein used published research on finger strength, speed, and dexterity to assign different effort costs to each key position per finger, resulting in a more biomechanically grounded optimization than layouts that treat all fingers as equally capable.
The layout was published as an open-source project with detailed documentation of its design methodology, making it one of the most transparent alternative layouts in terms of explaining why each key is placed where it is. This academic rigor distinguishes Engram from layouts designed primarily through intuition or community iteration.
Design Philosophy
Engram assigns each of the 30 key positions a precise effort cost based on which finger reaches it, accounting for differences in finger strength (the pinky is weaker than the index), reach direction (curling is easier than stretching laterally), and row-stagger geometry. It then optimizes letter placement to minimize total weighted effort across a large English corpus.
The layout emphasizes hand alternation — switching between left and right hand on consecutive keystrokes — even more than Dvorak. It also accounts for the fact that certain finger transitions are harder than others: moving from the ring finger to the pinky is harder than from the middle finger to the index, for example. This nuanced cost model produces a layout that may look unconventional compared to Colemak or Dvorak but is carefully grounded in measured biomechanics.
Who Engram Is Best For
Engram is a strong choice for typists who value a research-backed approach to layout design and want a layout that accounts for individual finger differences. It appeals to the analytically minded and to people who find that other alternative layouts still put too much strain on weaker fingers.
Typists who want a layout grounded in biomechanical research rather than community consensus
People who experience strain specifically in weaker fingers (pinkies, ring fingers)
Layout enthusiasts who appreciate transparent, well-documented design methodology
Writers who type long-form English and want optimized hand alternation
Switching from QWERTY
Engram rearranges nearly every key from QWERTY, including some punctuation positions. The transition takes 2–3 months of consistent practice, similar to Dvorak. Because the layout's logic is based on biomechanics rather than minimal change from QWERTY, there are no preserved shortcut positions — plan to remap or relearn Ctrl+Z/X/C/V.
SureTyping's lesson paths provide structured Engram practice that builds from home row outward. The AI trainer is particularly useful here because Engram-specific practice material is harder to find than for more popular layouts.
How to Practice on SureTyping
Begin with the home-row track to internalize Engram's core positions, then expand through the upper and lower rows. SureTyping's layout-aware keyboard preview shows you exactly where each focus key sits on Engram before every drill. After completing the guided curriculum, use custom training to continue refining accuracy on the specific letter transitions that Engram's design is built to optimize.
