To be more productive in Vim, you can use the following tips and techniques:
Learn the basic Vim commands: Vim is a modal text editor, which means that it has different modes for inserting text, navigating the document, and issuing commands. To be more productive in Vim, it is important to learn the basic commands for each mode, such as "i" for insert mode, "h", "j", "k", "l" for navigating the document, and ":wq" for saving and quitting.
Use the "h", "j", "k", "l" keys to move the cursor: Instead of using the arrow keys to move the cursor, you can use the "h", "j", "k", "l" keys to move the cursor left, down, up, and right, respectively. This can be more efficient than using the arrow keys, especially if you are using Vim on a remote server over an SSH connection.
Use the "f" and "t" commands to quickly move to specific characters in a line: The "f" command allows you to move the cursor to the next occurrence of a specific character in the current line, and the "t" command allows you to move the cursor just before the next occurrence of a specific character. For example, to move the cursor to the next occurrence of the letter "a" in the current line, you can use the "fa" command.
Use the ":%s/old/new/g" command to quickly replace text: The ":%s/old/new/g" command allows you to replace all occurrences of the text "old" with the text "new" in the current file. You can use the ":%s/old/new/gc" command to ask for confirmation before replacing each occurrence.
Use the "n" and "#" commands to search for the word under the cursor: The "n" command searches for the word under the cursor forwards, and the "#" command searches for the word backwards. This can be useful for quickly navigating the document and finding occurrences of a specific word.
