Neovim Visual Mode & Macros: Bulk Editing Superpowers

Unlock powerful bulk editing techniques in Neovim by mastering visual modes and macros. Learn how to select text in character, line, and block modes, perform multi-line edits efficiently, and automate repetitive tasks using macros and registers.

Code

" Example: Visual character mode to delete and paste
v          " Enter visual character mode and select text
d          " Delete the selection (cuts it to unnamed register)
p          " Paste the deleted text after the cursor

" Visual line mode with substitution
V          " Enter visual line mode and select lines
:s/old/new/g  " Substitute 'old' with 'new' in the selection

" Visual block mode to insert text at start of multiple lines
Ctrl-v     " Enter visual block mode and select a column
I          " Insert text before each selected line
Hello<Esc>  " Type 'Hello' and press Esc to apply insertion on all lines

" Macro recording and playback
qa         " Start recording macro into register 'a'
iHello<Esc>  " Insert 'Hello' at cursor position
q          " Stop recording
@a         " Replay macro 'a'
10@a       " Replay macro 'a' ten times

" Using named registers
"ay        " Yank selection into register 'a'
"ap        " Paste from register 'a'
"+y        " Yank to system clipboard
"+p        " Paste from system clipboard

" View contents of registers and macros
:reg a     " Show contents of register 'a'

Key Points

• Neovim has three visual modes: character (v), line (V), and block (Ctrl-v) for flexible selections.
• Visual mode commands like d (delete), y (yank), and :s (substitute) operate on the selected text.
• Visual block mode supports multi-line edits including block insert (I), append (A), and change (c).
• Macros recorded with qa...q automate repetitive edits and can be replayed multiple times with @a and counts like 10@a.
• Named registers store yanked text or macros, accessible via "a, "0, and system clipboard with "+ for efficient text management.
