Right now I use intellij for my main development work; I use some keyboard combinations where applicable (and changed the keymap to Sublime Text because I've used it and its derivatives (vs code mainly) for the better part of my career.
I don't have a dedicated flow for task tracking. Right now for work we use Phabricator, it's a bit awkward because it's a heap of independent modules built on top of each other, but it met our requirements (free, open source, self-hosted, not shit).
For a while I used a todo.txt addon in Sublime Text, which worked great; haven't been able to find a good alternative to it.
Used Wunderlist for a while, but I couldn't find my finished tasks without paying and it's been discontinued. Same with Todoist, minus the discontinued-ness.
Anyway, I don't think keyboard-based tools for me; I'm pretty good at typing if I do say so myself (~120wpm according to online tests / typeracer and co), but I haven't developed the mental capacity to remember all the keyboard shortcuts for emacs or vim.
I also didn't grow up with *nix systems, commandline only became a thing once I started my education and career ~15 years ago.
