Keyman VS Hot Virtual Keyboard

Keyman is very popular among linguists, if you still prefer a keeb that will input IPA Unicode by itself, you can get a QMK compatible keyboard (like this), but you'll need to program it, as in write the code yourself. Source: about 1 year ago

SIL's Ukelele is a popular app for creating custom keyboard layouts on macOS. SIL also recommends Keyman if you're looking for a cross-platform app for creating custom keyboards. Keyman already supports thousands of languages so they might already have a keyboard for the languages you need. Source: over 1 year ago

While I haven't used it myself, I have heard that Keyman is highly flexible and extensible, so it may allow OP to create a layout in its own format that has the desired behavior. Keyman was originally a commercial product, but SIL (which had long advocated its use) acquired it in 2015 and made it free shortly thereafter. The original developer seems to still be part of the team working on it for SIL. Source: about 2 years ago

For Tam Thư, specifically the phonetic Latin Quốc Ngữ and Ký Âm, I'm working off of an existing keyboard distribution platform called Keyman. It's free and open source with good developer's guide. For my case, Vietnamese typing is a bit complicated with many key sequences that makes modifications to a base glyph, and Keyman is a fit tool for that in my experience. It also follow the principle of "write once, run... Source: about 2 years ago

Because Tam Thư is in fact 3 writing systems combined, I made 3 separate IMEs/keyboard layouts for each of them: 2 phonetic keyboards for Latin Quốc Ngữ and Ký Âm Tự using Keyman, and 1 logographic keyboard for Hán Nôm (think of it as Vietnamese Kanji, you can read more about its history here) using Rime. This results in the user having to install both Keyman and Rime + my IME package for each of the two. Then... Source: about 2 years ago

Thanks for all the ideas and helpfulness! Unfortunately, voice recognition wouldn't work because I live on a ventilator and don't have a voice. Single-button solutions might do though, but that's a really slow method... For an on-screen keyboard, I have Hot Virtual Keyboard, which is really good and customizable. Fortunately, I manage with it and the mouse well enough, but there are situations when I can't use the... Source: almost 2 years ago

I'm playing with my PS5 via Remote Play and I don't use anything else but my mouse and two mechanical switches. (Plus some accessibility software like Hot Virtual Keyboard and Alt Controller.) Still, I play racing games, Assassin's Creed, and even offline fps games. Source: about 2 years ago

Hi, I'm using Hot Virtual Keyboard. It's totally customizable. I can even play racing games with it. :) (Here's a video about that: link). Source: about 2 years ago

Most of the time, I use Hot Virtual Keyboard and Alt Controller because I can't move my body parts to be able to use physical devices, only the mouse and in an unusual way. Lately, I got some mechanical switches and figured out how can I press them with my eyebrows, so I have two additional buttons now. Sometimes, I also use Tobii eye tracker with Project IRIS, or AutoHotKey, but for gaming, I need them rarely.... Source: about 3 years ago
