Multiline Editing with Visual Block Mode

Visual Block mode is a game-changer when you need to make the same changes to multiple lines at once. Here's how to add or remove text in a block:

• Enter Visual Block Mode: Position the cursor at the beginning of the first line you want to modify. Press ctrl-v.
• Select the Block: Use the down and up arrow keys to extend the selection vertically to include all the lines you want to modify. The width of the selection will be determined by how far you move the cursor horizontally from the starting position.
