Vim (Vi IMproved) is a highly configurable text editor widely used on Unix-like operating systems and Windows. It’s based on the original vi editor, but with numerous added features and improvements. In Vim, operation parameters are used to specify the scope, direction, and other characteristics of actions. Here’s a breakdown of common Vim operation parameters:
- Numeric Prefix
A numeric prefix can be combined with most commands to repeat the command a specified number of times.
Examples:
5j: Move down 5 lines.
2dw: Delete the next two words.
- Motion Commands
Motion commands are used to navigate within a file. Common motion commands include:
h, j, k, l: Move left, down, up, and right by one character, respectively.
w: Move forward to the beginning of the next word.
b: Move backward to the beginning of the previous word.
e: Move forward to the end of the current word.
$: Move to the end of the line.
0 (zero): Move to the beginning of the line.
G: Jump to the last line of the file.
gg: Jump to the first line of the file.
- Text Objects
Text objects allow you to select specific blocks of text, such as words, sentences, paragraphs, text within quotes, and more.
Examples:
aw: A word, including spaces.
