Vim has been my go-to editor for the last 1.5 years, yet I am still learning something new. Recently I learned about "Insert Normal" mode and I'd like to share how you can use this mode to code faster in vim!
Feedbacks are highly appreciated. If you think of more ways to save keystrokes using this mode, feel free to share in the comments!
What the heck is insert-normal mode?
Glad you asked!
It is a mode in insert mode where you can execute normal mode commands. Instead of switching modes from insert -> normal -> (do normal mode stuff) -> insert, you can execute normal code commands while remaining in insert mode.
All you need to do is to press C-o while in insert mode.
How can you tell that you're in insert-normal mode? In insert mode, you can see -- INSERT -- indicator on bottom left. If we press C-o, it will change into -- (insert) --.
Important: you can only execute one command in this mode. After executing a normal mode command, you're back to insert mode.
Even with this limitation, this is still a powerful feature. Let's give some examples what we can do with insert-normal mode.
Example 1: Navigating while remaining in insert mode
Let's say while typing, you wanted to add a word in the beginning of current line. Do C-o 0 to jump to the beginning of the line, add the word, then jump back with to the end with C-o $.
Maybe you are adding something after comma in the same line, just do C-o T , and you'll jump right after the comma. C-o $ to jump back to the end.
You can always mix it with other vim motions. I find H, M, L, [], () useful for quick navigation.
Example 2: Centering screen
I am typing this article in vim. As I am typing this, I am at the bottom of the screen. I can center my current position by doing C-o zz.
Example 3: Repeating characters
Say I want to type * 100 times. I can just type C-o 100 i * <esc> (the downside is, this will force you to leave insert mode).
Example 4: Deleting faster
If I wanted to delete a block of text from my current position to an anchor, say a comma, I can just do C-o d T ,
What's next?
These are some ways we can take advantage of insert-normal mode.
I am interested to learn how other devs can take advantage of insert-normal mode. What other ways do you guys think insert-normal mode can be used?

Nice! Let me add my favorite here:
Shift-j to merge next line
gqip to reformat paragraph
gqj to reformat over next line
These together are mostly enough to avoid manual reflow to honor line length limit.
Good use cases! I never really knew about the last two - thanks! Always learning something new about vim.
I've known about insert-normal, but I never used it really. I've remapped to and my brain is already wired to leave insert more whenever I pause. But thanks for the insight, it's always helpful to know more about vim!
I've been vimming for ... I don't know how many years. probably since 1994 because I see that it was in Slackware 2. I didn't know about this. Thanks!
Mind you, now that I know about it I'm not sure whether I'll use it.
<ESC> command iis soooo deeply ingrained in my muscle-memory that I'm not sure I'll ever be able to stop doing it :-)I agree. It is ingrained in my muscle memory too - and I haven't used vim for more than 2 years!
Learning to be more thoughtful when I'm typing and breaking from the
<Esc> normal-commandhabit slowly... :) This is going to take a while!Thx for sharing !
What I find helpful is mapping some combinations to shortcuts in insert mode to ease cursor movement and/or scrolling :
Woah. This is mind-blowing. I'll have to try this!
Despite having used Vim for almost a decade (possibly more, I don't quite remember exactly when I started using it), this is actually completely new to me.
OTOH, I'm not too surprised when I find something I didn't know about Vim (or just
viin general), I still average about one new thing I learn about it every week or so these days, but then, I never really went out of my way to learn anything but the absolute basics originally (and it was Nethack, not Vim, that got me in the habit of using hjkl for movement).Nice, now I can stop invoking Anubis every time I want to switch to another tab while staying in insert mode ;-)
Haha, good use case! Stay away from the underworld >:)
My favourite is C-o o or C-o O, starting on next/previous line.
I used
o/Oall the time and didn't think of that. Good rec!๐ฒ๐ฒ๐ฒ๐ฒ๐ฒ๐ฒ thanks for sharing!!!!! it's a real discovery for me, I really love it.
Haha, glad you found it helpful! It totally changed my workflow when I discovered this too!
There's mine:
Haha nice!! I thought of mapping my arrow keys as well, good call!
