TONS of cool tips: https://www.cs.oberlin.edu/~kuperman/help/vim/windows.html

Aligning text indentation, such as with XML, YAML, and JSON:

• Use ]p to paste into the correct location. VIM will automatically indent to the same position as the line the cursor starts on

• When pasting from outside the document, can yank the lines back out, then use ]p to repaste them into place

Save text (and possibly commands) into a register:

• Use double-quote and any lower-case letter, then yank or delete

• E.g. "ayw to save the current word into the register a

• To paste, use double-quote and the letter, then paste

• NOTE: Can use the upper-case letter to append (repeatedly, if needed) to what’s already saved in that register

• Use :reg to view the contents of all registers (useful when working with lots of bits of text)

• One guide says can access the Windows or Linux system clipboard with "+ or "*, but I couldn’t get them to work

To record a macro:

• (In command mode)

• q # To start recording

• The letter to assign the macro to, i.e. a

• Perform the series of actions

• q # To stop recording

To run a macro:

• (In command mode)

• @ + the letter the macros is stored under, i.e. @a

To run a macro over a set of lines:

• (In last line mode)

• Example running a macro over lines 5 through 10 :5,10norm! @a

• Example running a macro over lines 5 through the ened of the file :5,10norm! @a

• Example running a macro over all lines in the file :%norm! @a

• Example running a macro over all lines that match a pattern :g/pattern/norm! @a

Visual Mode:

• (In command mode)

• v # (lower case) Select block character by character

• V # (upper case) Select block line by line. Cursor can be anywhere on the line

• Ctrl+v # Selects vertically oriented blocks

  • All of the operations are available, but not very useful

  • Huge strength of this mode is that is makes it easy to check indentation across man lines

    • Great for YAML, jSON, and XML files

• Navigate cursor as normal to select block

• Operations available:

  • y # yank

  • d # delete

  • c # change, effectively the same as cw

  • > # increase indentation of the block

  • < # decrease indentation of the block

  • : # apply last-line command to the block

Split Windows:

• :e <filename> # edit new file

• :split filename # split window horizontally and load another file

• :vsplit filename # split window vertically and load another file

• Ctrl+w Ctrl+w # move cursor to another window (cycle)

• Ctrl+w= # make all windows equal size

• :hide # close current window
