Sure you can! I'd take the opportunity to learn both touch typing and Colemak then. I do suggest you learn to use 9–10 fingers properly while you're at it. Using your pinkies is going to feel harsh at first, but they're worth it. Pinkies are agile fingers, if not too strong. Some Colemak users coming from QWERTY struggle at first but when you get used to it you'll enjoy it a lot more. Taking the plunge into Colemak, it's worth doing it right.

I don't remap Vim keys at all, since it's useful to find Vim on an install and just start using it without having to setup a config first. The arrows are entirely not a problem, and I use Extend anyway. Look it up on https://dreymar.colemak.org if you're curious.

Yes, you will if you want to. There are people who can fluidly switch between three or more layouts at top speed; Jashe Poon is the most extreme. But as for me... I don't want to type QWERTY any more whenever I can avoid it. It's so ugly and uncomfortable. I can type it at a decent enough speed for my purposes, by looking at the keys. I need no more, and if I have to type for a longer time at another computer I can always use EPKL or a USB-2-USB QUICKIE device.

If you haven't already, read about those in the BigBag. Come to think of it, there's an article about QWERTY memory on its Links page too, if you're interested.

Thanks for all the advices.

One interesting thing that i observed today is that in my workflow (in linux/unix) i feel that i lost some of the key combos like, `cd`.
I can combo with my index and middle finger and now i cant.

I think i need to alias `cd` to `c`, similar to when i aliased to `ls` to `l` on my qwerty layout. The first time i typed `cd` and `ls` with colemak today was so weird. :p

Probably because C is in practice a lot easier with the index finger, so for for most people, "cd" an awkward same-finger bigram in vanilla Colemak.

Colemak-DH (or vanilla plus angle-mod) to the rescue...

I recommend practicing for 10 minutes every day for a couple of months, and switching when you've reached two thirds of your previous typing speed. Repeat the lessons until you reach at least 97% accuracy without hesitating.

While you're touch typing many keys will be hidden by your fingers, so you'll have to lift them every time to see the letter below. It will also make it more difficult to adapt to working on other people's computer, whether typing in QWERTY or Colemak. I don't recommend physically moving the key caps because it will move the bumps on the keys below the index finger ("F" and "J" keys on QWERTY). If need help specially with COLEMAK you can practice typing with one words per minute test tool that will help you a lot.
