We can also goto insert mode from normal mode by pressing `a` or `o`. Pressing `a` will move the cursor 1-step left and apply insert mode whereas pressing `o` will apply insert mode in the new line.
Visual Mode: This mode can be accessed by typing `v` from normal mode. Visual mode allows us to select the text, select line, or block. This mode is useful for identifying chunks of text to be manipulated.
