<C-d> in command mode presents an auto-completion listIn command mode you can specify a range of lines to operate on, based on patterns, rather than absolute (or relative line numbers). This can be a great way to isolate changes without looking up the individual line numbers.

+staticBalancing many disparate tasks is good for my morale (“Wow! If I get bored with this one thing, I can just do something else!”), but feeling “behind” is most decidedly not good for my morale. Timeblocking and scheduling are great, but they require discipline. I like to think that I am effectively entering into a short-term contract with myself. If the terms aren’t clear, the chances of failure go up (significantly). Interestingly, I think this scenario represents a conflict of interest: I am basically the party responsible for monitoring that contract, as well as the one actually executing the work.
Besides having a clear plan (a statement of work) I think the next biggest concern involves distractions. In my experience, you can’t get rid of distractions, but you can be judicious about what distractions you choose to entertain. That gets to the same end-goal of choosing when to focus on distractions, but puts a different emphasis on the problem.
The “hard” part (to me) is that developing the intuition of what to do (and when) is much easier said than done. Maybe because it is a constantly moving target?

c instead of deleting and inserting in visual modeUsing the c change action in visual mode is very convenient! For some reason I often neglect that action when operating in visual mode, instead opting for two actions: delete and insert. This seems like a habit worth breaking!

copy command doesn’t use a registerThe copy command doesn’t use a register. This is useful for not overwriting the current value in the default register - you might not need to run the copy command, but it might help keep your registers clean.
q: opens the command history windowq: opens the command history window. When this window is open, it maintains exclusive focus.
From Normal mode, R activates Replace mode, which behaves a lot like Insert mode, except that it allows you to effectively type over existing content. This is different from r, which is a single character replacement (ending back in Normal mode) - R requires you to deliberately exit back to Normal mode.
