Instead when choosing another layout, it might be best to ignore the metrics and choose the layout philosophy that you agree with the most. Then the different metrics mean you end up comparing apples with oranges.
The truth is that, the layouts differ because the philosophy used to create the layout differs, and then the metrics are measuring different things. When investigating the different layout websites, you’ll see various metrics, and claims about how the layout is better than the rest.
On the left hand, IE and EA are adjacent key inward rolls (EI and AE are less common so are outward rolls).The 2 most common letters are on the middle fingers: E (left middle finger), and T (right middle finger).Then there are adjacent letter key trigrams such as:Īnd a word such as THOUGHTS, can be broken down into the adjacent key bigrams TH, and OU, then finished with the adjacent key trigram HTS.Įngram also has symmetry on the home keys amongst the right and left hands. Note - words such as COULD, SHOULD, and WOULD.Īlso there are same finger-type bigrams for common words such as: Note - TH is the most commonly used bigram in English. ie the middle fingers.Ī key feature of the layout is that many common bigrams are same-hand adjacent keys. However there are some common shortcut keys in easier positions for the left-hand and they are:Īs the letters E and T are the most common in English, those have been placed on the strongest finger of each hand.

#Qwerty keyboard layout mod
So Colemak with Angle Mod looks like the layout below:
#Qwerty keyboard layout iso
This concept is ideally for an ISO keyboard, but can be made to work for an ANSI keyboard too.įor the ergonomic finger technique to work for the Colemak layout, the finger assignment will change to the following: The result being that the fingers on the left hand can more ergonomically reach the keys on the bottom row when using the Colemak layout. The idea behind the Angle Mod is to promote a more comfortable, symmetrical typing posture on standard keyboards. So a modified Colemak layout was created, named Colemak Mod-DH to de-emphasise the centre columns.ĭe-emphasising the centre columns will reduce lateral movement of the pointer fingers, leading to less fatigue of those fingers.Ĭolemak Mod-DH actually has 2 core features: There was some concern that the common bigram ‘he’ was causing unnecessary fatigue when using Colemak. Essentially there are 2 paths on offer depending on how long you want the home row:įor those typists who want to keep using the Qwerty letter mask (9 letter home row), but swap a selection of keys to reduce the typing effort choose either of the following:Ĭarpalx QWKRFY - only 5 key pair swaps and keeping ZXCV fixed.Ĭarpalx QWYRFM - only 10 key pair swaps and keeping ZXCV fixed.Ĭarpalx QFMLWY - many key swaps for 42.6% less effort than Qwerty, but ZXCV is not fixed.įor those typists who prefer a 10 letter home row for Colemak, and are already be using the Colemak layout, then choose either of the following:Ĭarpalx GYLMWP - retain 9 letter keys the same as Colemak and ZXCV fixed.Ĭarpalx PBFMWJ - retain 11 letter keys the same as Colemak and ZXCV moved.įor those typists who will accept the most key swaps to get the biggest benefit, then choose either of the following:Ĭarpalx QGMLWY - 10 letter home row, and ZXCV fixed to get 44.3% less effort than Qwerty.Ĭolemak Mod-DH to de-emphasise the middle columnsįor some users of Colemak, some felt that all was not well, even with the 8 letter home keys.
