Different ways to get into insert mode

There are different ways to get into insert mode besides i. Here are some of them:

i " insert text before cursor I " insert text before the first non-blank character of the line. a " append text after cursor A " append text at the end of line o " starts a new line below cursor and insert text O " starts a new line above cursor and insert text gi " insert text in same position where last insert mode was stopped in current buffer gI " insert text at the start of line (column 1) Enter fullscreen mode Exit fullscreen mode

Notice the lowercase/ uppercase pattern.

Different ways to exit insert mode

There are several ways to exit insert mode back to normal mode.

<esc> " exits insert mode and go to normal mode Ctrl-[ " exits insert mode and go to normal mode Ctrl-c " like Ctrl-[ and <esc>, but doesn't check for abbreviation Enter fullscreen mode Exit fullscreen mode

Another common technique is to remap your <caps lock> key to behave like <esc>.

Repeating Insert Mode

You can give a count before you enter insert mode. For example:

10i Enter fullscreen mode Exit fullscreen mode

Then if you type "hello world!" and exit insert mode, it will repeat the text "hello world!" 10 times. This works with any methods you use to enter insert mode (10I, 11a, 12o)

Deleting chunks in insert mode

There are different ways to delete while in insert mode besides <backspace>:

Ctrl-h " delete one character Ctrl-w " delete one word Ctrl-u " delete entire line Enter fullscreen mode Exit fullscreen mode

By the way, these shortcuts also work in command-line mode and Ex mode too, not just vim.

Inserting from register

Registers are like spaces in memory to store texts. To learn more about registers, check out :h registers.

Vim can insert contents from any register with Ctrl-r plus register symbol. You can use any alphabetical character a-z for named register. To use it, if you want to yank a word to register a, you can do:

"ayiw Enter fullscreen mode Exit fullscreen mode

To insert content from register a:

Ctrl-r a Enter fullscreen mode Exit fullscreen mode

Vim also has 10 numbered registers (0-9) to save the most recent 10 yanks/deletes. To insert content from numbered register 1:

Ctrl-r 1 Enter fullscreen mode Exit fullscreen mode

In addition to named and numbered registers, here are another useful register tricks:

Ctrl-r " # insert the last yank/delete Ctrl-r % # insert file name Ctrl-r / # insert last search term Ctrl-r : # insert last command line Enter fullscreen mode Exit fullscreen mode

Vim has an expression register, =, to evaluate expressions.

You can evaluate mathematical expressions 1 + 1 with:

Ctrl-r =1+1 Enter fullscreen mode Exit fullscreen mode

You can use expression register to get the value of your vim settings. You can do this with setting name prepended with &. For example, to insert what undolevel setting you currently have, you can use:

Ctrl-r =&undolevel Enter fullscreen mode Exit fullscreen mode

Another way to get values from registers is with @ followed by register symbol.

Ctrl-r =@a Enter fullscreen mode Exit fullscreen mode

This works with any registers mentioned above, including ",/,%. I think the first method is a little faster, but I just want to show a different way.

You can also evaluate basic vim script expression. Let’s say you have a function

function! HelloFunc() return "Hello Vim Script!" endfunction Enter fullscreen mode Exit fullscreen mode

You can evaluate its value just by calling it.

Ctrl-r =HelloFunc() Enter fullscreen mode Exit fullscreen mode Scrolling

Did you know that you can scroll while inside insert mode? You can use Vim’s Ctrl-x sub-mode.

Ctrl-x Ctrl-y " scroll up Ctrl-x Ctrl-e " scroll down Enter fullscreen mode Exit fullscreen mode Autocompletion

Vim has a built-in autocompletion. Although it is not as good as intellisense or any other Language Server Protocol (LSP), but for being so lightweight and available right out of the box, Vim’s autocomplete is a very capable feature.

You can use autocomplete feature in insert mode by invoking Ctrl-x sub-mode.

Ctrl-x Ctrl-l " insert a whole line Ctrl-x Ctrl-n " insert a text from current file Ctrl-x Ctrl-i " insert a text from included files Ctrl-x Ctrl-f " insert a file name Ctrl-x Ctrl-] " insert from tags (must have tags) Ctrl-x Ctrl-o " insert from omnicompletion. Filetype specific. Enter fullscreen mode Exit fullscreen mode

You can also autocomplete without using Ctrl-x with:

Ctrl-n Ctrl-p Enter fullscreen mode Exit fullscreen mode

To move up and down the pop-up window, use Ctrl-n / Ctrl-p.

Autocomplete is a vast topic in Vim. This is just the tip of the iceberg. To learn more, check out :h ins-completion.

Executing normal mode command

Did you know Vim can execute normal mode command while inside insert mode?

While in insert mode, if you press:

Ctrl-o Enter fullscreen mode Exit fullscreen mode

You'll be in insert-normal sub-mode. If you look at mode indicator on bottom left, normally you will see -- INSERT --, but Ctrl-o will change it to -- (insert) --. You can do one normal mode command. Some things you can do:

Centering and jumping

Ctrl-o zz " center window Ctrl-o H/M/L " jump to top/middle/bottom window Ctrl-o 'a " jump to mark 'a' Enter fullscreen mode Exit fullscreen mode

Repeating text

Ctrl-o 100ihello Ctrl-o 10Ahello Enter fullscreen mode Exit fullscreen mode

Executing command line

Ctrl-o !! curl https://google.com Ctrl-o !! pwd Enter fullscreen mode Exit fullscreen mode

The possibility is endless.

Conclusion

I think this is a good place to stop. Vim's real strength is in its modal nature. While most editors only have one mode, vim has different modes for different context. Insert mode is one of them.

If you are coming from another text editor/ IDE, it can be tempting to stay in in insert mode. I think spending too much in insert mode is an anti-pattern. Try to get used going to normal mode when pausing.

Vim's insert mode still contains many useful features apart from normal mode. You can repeat phrases, delete chunks, access registers, scroll, autocomplete, and even execute normal mode commands inside this mode. Use these to boost your productivity.
