this mouse is interesting, in that it has what seems deep buttons.

i've been thinking that mouse should have deep buttons as keyboard, because they require less effort to click. (you'd appreciate this line of thought only if you have Repetitive Strain Injury)

i haven't looked into this mouse yet. Need research. But putting it here now.

by the way, on linux, i use hover to activate window. Now on Mac, i use the dwell feature (automatically click when pointer is not moving). So, i basically NEVER do mouse click now. However, the auto click feature has its own issues, that you are prone to click by mistake. But i persisted. Basically, you have to train, carefully, when to move the mouse, and where you can rest the pointer.

Ok, I see your reason. But let me give alternative view.

Vast majority of people, will never, ever, change keycaps. Now, even mechanical keyboard fans, I'd say, 99% of those who bought mechanical keyboards, will never, ever, change keycap.

who changes keycaps? the people here, which is a very niche group, like, comic book collectors or novelty pen collectors.

and what keyboard that lets you change keycap? not that many! well, vast majority of them are just cherry mx, and 99.99% of those are standard IBM PC flat keyboards. The few exceptions are, ergodox, variations, maltron, truly ergonomics keyboard, and that's almost about it.

This keycap changing love is actually preventing keyboard progress, because by basing on Cherry MX, it prevents the flow of newly designed key switches. For example, Logitch's Romer-g switch, which fixed the cherry mx problem of not able to put led in center thus light leak. But, many will complain, cannot change keycaps!!

as to X-bows design, I disagree with your heavy handed dislike. For example, first consider keyboard innovation. This is very rare. Even in this explosion of ergonomic mechanical keyboard since Truly Ergonomic keyboard about 5 years ago, we have maybe just 1 new design per year, and X-Bows is one of the better ones, and arguably better than ergodox, by introducing back the physical arrow keys and function keys. Let's remember, consider the keyboard user population, I'd say 99% would want physical arrow keys.

and then, stupid center key, huh? there are many keyboard designs, either split, or 1 piece. If we go by one piece and compact, you have this center key situation. What would you put in the middle? a triangle key? sure, I think that adds 1 key, and might be better. But every cranny of decision we can dislike.

... but let's stand back and look at the broader picture of /r/mechanicalkeyboard/ . Ask an average keyboard user, who suffer from Repetitive Strain Injury pain, and want ergonomic and mechanical keyboard. What do they think of this forum? Answer: crazy sixteens! But even among us keyboard fans, many of us find it crazy too. You (guys) attack this keyboard, while the dumb of the dumb and the dumbest the Happy Hacking Keyboard and Planck, kept appearing here day after day with stupid shoes!

linux keybinding = pain

1, linux is truly a pain in the ass. On macOS, 3 hours = 5 years worth of learning linux keybinding howto.

2, on linux, i thought, if u r hardcore programer, you'd be able to do far more in keybinding than Mac or windows. Not true at all.

3, i learned the hard way. On linux, there are 10 ways to do it. And the ways are among political factions of desktops X11 xorg ubuntu etc.

4, linux has little documentation. If so, outdated. You spend hours scan stackoverflow and some 10 years old doc online or arclinux page

5, and everytime u complain, there arise an army of linux fanatics defending n flaming u. from where's your code to that's not linux = kernel

6, on the Mac, there are typically several utilities, free, sometimes open source. In 5 min, you can do what you want. Far robust + reliable

Mouse's 4th and 5th Buttons on MacOS

On macOS, mouse's 4th and 5th buttons by default work as middle click. Interesting. and nice. Middle click to open link in new tab.

though, it'd be better is one of them is Back button by default.

you can set them to do whatever. Use USB Overdrive, see Mac: Key Remapping and Keybinding Tools

problem with extensive customization

one problem with extensive customization is that, if you have a machine, OS, or keyboard, and if you haven't used it for a while, you forgot how to operate it. All standard keys and shortcuts are not there, because you removed them for utter efficiency of using the key spots.

the customization may be one or more of the following:

also, for each OS, there are diverse mechanism to remap keys. For example, Standard OS mechanisms, using standard keyboard layouts, or using various third-party software tools. (For example, on linux, there's xmodmap, xkb, and different window manager has different ways. Similarly, diverse on macOS or Microsoft Windows.)

what are the situations you would forgot keys? It just happens. Because different keyboard e.g. Kinesis Advantage2 Keyboard, Truly Ergonomic Keyboard, and different computers (work, home, laptops), it's common for one of the keyboard or machine you may not have touched for a month or two.

So, one thing i learned is that, when you customize extensively, try not to remove the standard keys that comes with the OS.

as for keyboard, if you can relabel them, that's best. Else, keep a picture of your remapping.

trackball vs mouse

after 2 years with trackball, i finally decided, mouse is actually more precise and faster. I really wanted to like trackball.

trackball is nice if you don't require precision, and you want ease of use. It's really easy just to roll it. But as soon as you need to aim at tiny x or buttons, mouse is more precise.

the 2 trackballs am using are:

of the two, the M570 is better, because it has scroll wheel.

also, on the question of thumb trackball vs index finger trackball, I find myself preferring thumb trackball.

the other issue with trackball is that you need to clean it every 3 weeks. Else, the ball becomes sluggish to roll.
