Common vim commands, vim

VIM is generally divided into several modes to distinguish whether the input is a text or a command through different modes:
1. Normal mode (common mode, c-mode ):
Once you enter VIM, it is in c-mode. You can only enter commands and text. These commands may be commands for moving the cursor, editing commands, or searching for replacement commands.
2. Insert mode (I-mode ):
Press I/a/o to enter the I-mode. You can enter text in the editing area, and Press Esc to return to the c-mode.
3. Ed mode (common-line mode, e-mode ):
Press: enter e-mode. The VIM command prompt area (bottom of the editing area) has a colon: appears. You can enter the command line command and Press Esc to return to c-mode.
4. replace mode
Press R to enter the replacement mode, and Esc returns c-mode

Tips: the Esc key is frequently used in vim. You can change the function of the Esc key and the Caps key by modifying the registry.

Note: uppercase commands ignore punctuation marks.
