I took typing for one semester in high school, 57 years ago. Despite so many years of touch typing, I’ve never been a fast typist. I haven’t slowed down much, but I type around 45 WPM just as I did over 50 years ago. I’ve tried to type faster, but I think my hands are simply not very dexterous.<p>Because of my slow typing, I probably don’t notice any decline in ability compared to those that were unusually fast in their youth.<p>Depending on the type of work you do, perhaps a more powerful text editor would be useful. I would suggest Neovim or Emacs. Both are excellent in their own way and both have extensive facilities for handling auto completion of common phrases or markup text and use of abbreviations, etc.<p>Neovim is a modern version of an editor (vi) that has stood the test of time as one of the fastest editors for navigating over and manipulating text. Shifting between its different modes, each optimized for particular tasks, means it will take a couple of weeks if use to feel natural. The editor itself won’t increase your basic typing speed, but you will be able to fly though your documents correcting and rearranging words and sentences faster than any other tool out there.<p>Emacs is another ancient editor that is hard to master. Moving and editing text are out of the box a bit slower than Neovim, but the hundreds and hundreds of available packages and extensions make it a high power tool for managing any files or folders on your computer. Like the keys used in Neovim? Emacs can be configured to work the exact same way with a couple of packages. Need to rearrange your directories and rename a bunch of files? There’s really no file manager as good at this as Emacs. Outlines, agendas, check lists, bookkeeping, version control, taking dictation, editing 100 files at the same time, all of this is possible with Emacs. Basic Emacs is probably a bit easier to pick up than Neovim, but it will take time to settle on your own configuration composed of the packages you like best.<p>You don’t need to be a programmer to use either of these editors, but if you are, they can be easily tweaked to operate however you’d like. Both of them and the packages that expand their capabilities are open source. They run on MacOS, Windows, Linux and even other OS’s and cost nothing.<p>These editors may not increase your raw WPMs, but they may provide a platform that you will find almost as productive as before due to their many features.
