In normal mode, enter ":" (General Command) and "/" (Forward search) or "?" (Reverse search) to enter this mode. In command mode, enter the Enter key. 3) insert mode, used for text input; in normal mode, type "I" (insert) or "A" (append) you can enter the insert mode (there are also some commands, such as "C", you can also enter the insert mode, but these commands have other functions ). 4) visible (visual) mode, used to select text blocks; you can enter "v" (lower case) in normal mode to select by character, and enter "v" (upper case) or press Ctrl-V to select by Square. 5) select mode: similar to the normal Windows Editor, select text blocks.
