I don't quite get what you're saying: The fingering for C and all other keys except VK_102 stays the same with the Angle mod. That's part of the beauty of it! It just lets you keep a better wrist angle. I certainly feel that the C reach is better and not worse with the Angle mod. It's 1/2 key either way but with the mod the reach is done without ulnar deviation.

Oh, I see: You've used the index finger for C. You cheater you. ;-) Well, unless your middle finger is having some special sort of problem I don't think it should cause any trouble. You'd have to learn the "proper" fingering then as you say but if it only concerns one finger that's done in a jiffy. Your finger balance should get a bit better too.

From a technical point of view, it's 6 more keys moved. From a typing point of view, it's just one very rarely used one (well, two keys in your case).

You're already using your own angle mod. It entails changing the fingering for the involved keys which I wanted to avoid, but it should give the same ergonomical benefits for the most part. Bigrams shouldn't be badly influenced I think, as the involved consonant bigrams aren't that common (SC is in fact one of the more common ones iirc, and your technique makes it a two-finger bigram which is an improvement).

A little load is taken from the pinky to the index finger, but I don't think it's dramatic. So all in all, the only major reason I can see for wanting to change your solution would be the B key stretch. You'll have to find out for yourself if you think it's worth it, really. If you float well and use the whole underarm to move laterally, that position isn't too bad I feel.

On the upside, I think you should be able to learn the ZXCVB angle-modded positions fairly quickly no matter what. And if you do, you'll get a nicer B stretch (at the cost of a little more confusion but what's life without confusion eh?). Somehow, the better wrist position will make the G stretch a little harder but you should already have noticed that using your technique?

Tip: They're not digraphs! Digraphs are Dutch IJ, Serbocroatian LJ, NJ and DŽ etc, which sometimes are represented by a single Unicode point. Generally, when you type two characters in sequence it's a bigram.

I have absolutely no qualms about the shortcuts, as they're usually typed as a separate chord anyway. The mental separation of reaching for a Ctrl+key combo makes it easy whether the ZXCVB keys are moved or not in my experience.

I wouldn't move the G. It's fine, especially with a bit of float in your technique. I just noticed it, is all. And after all, G is a fairly long march down the ETAOIN SHRDLU CMFGYP... road. ;)

Damn, that is a good point about D>P>G. I think the P position is slightly better than the D one and certainly no worse. Have you done any analysis on this?

The thing is, when Colemak was created the home row was considered very holy. So based on this, the D deserves to remain there. Nowadays, especially for people with long fingers (caveat!), the FPW and LUY positions are considered good too.

This loop shouldn't damage anything I can think of as the letters stay on the same finger. Moving 16 instead of 17 keys should be nice for the learners, too.

The only problem with that argument is people could likewise say, with its long heritage, Qwerty is holy, and messing with it is sacrilege.

I think it's worth identifying improvements where possible. Having gotten used to default Colemak now, I am also reluctant to make any significant changes, but this is one that I would consider. I previously mentioned it in the Workman thread, as it helps to de-prioritize the centre column to some extent, which is a common criticism Workman devotees level at Colemak.
