Vim's macro recording feature can automate repetitive operations, greatly improving editing efficiency. Recording macros: In Normal mode, press q followed by a register name a-z to start recording, perform a series of operations, then press q to end recording. Executing macros: @a to execute the macro in register a, @@ to repeat the last macro, 10@a to execute the macro 10 times. Viewing macro content: :reg a to view the content of register a. Appending macros: qA to append recording to the content of register a. Macros can combine multiple commands including movement, deletion, copying, pasting, etc. Practical use cases: batch code formatting, repetitive text processing, data transformation, etc. Macros are one of the essential skills for Vim advanced users, capable of automating complex editing tasks.
