Do you have different preferences regarding keyboards between heavy typing (long typing of texts without breaks) versus light/intermittent typing with often breaks (coding with thinking/looking for references, replying to short emails, googling etc)?

For me, it seems that I prefer different types, however I have not clarified yet for myself what the difference is - it does not seem to be just switch weight, but it is definitely one of the factors - e.g. I seem to like Unicomp (BS) or MX-style blue for longer texts, however I may prefer lighter keys (e.g. my new taihao apt soft click switch or some lighter better-quality rubber domes (BTC, Keytronic) for shorter, interrupted writing).

In other words, it seems that it is "getting into writing flow", what brings me pleasure from more heavy/tactile keyboards. Frequent interruptions, on the other hand, make their use unpleasant for me.

What are your opinions/experiences?

Typing is typing. If I don't enjoy typing on it for long periods of time, why would I enjoy typing on it for short periods? Perhaps it's just unfamiliarity rather than actually liking things for shorter times.

When heavy typing, I usually have another rhythm (more regular), another speed (quicker), a lot less interruptions. When I "short-type", I often break my typing with looking for info, thinking etc. I have to repeatedly "get into typing flow", I often write more slowly, have to re-write etc. And that is for me different feeling/experience (similarly like for somebody is gaming different keyboard experience from typing)

So of course, it is psychological (not physical) difference, however I would think that majority of things around keyboard preferences here are psychological/subjective.

I definitely have these preferences.

The amount that I type can vary a lot in a day, and sometimes it's just typing in sentences to people while, other times, it involves a lot of navigation key and modifier use (like writing SQL or something).

I haven't really narrowed down exactly what I like when. I really like heavy, very tactile or very clicky switches; however, I tend to get fatigued when I use them at work. Light clicky or even something like a Model M is easier to use for a full day for me. BOX Navies are awesome, but, after about four rounds of keyhero, my fingers start getting slow.

I've been using BOX Royals with SA caps for several weeks at work, and, while I love it, it does get rather tiring. I keep a board with Kaihl Low profile blues and an OK rubber dome in my desk draw just so I have something lighter to type on if it starts getting to me. Oddly, the Model M never bothered me, probably because it's perfect. It's just too loud to use in the shared office space I'm in now. I've thought about bringing my original MX Blue board back up to work, but it might be too loud also.

For what it's worth, I do think MX Reds are probably the best for gaming. I really hate linears for typing, but they are great for games. I do occassionally play games with clicky switches though, just not MX blues.

I type faster when I have tactile feedback allowing me to not bottom out while still being positive the key actuated.

However, this is totally down to preference. Of course, it may all be in my head, but personally, I feel I type faster this way.

I find a linear switch to be nicer for typing messages quickly but for prolonged typing I definitely prefer something with tactility.
