  1. v to begin character-based visual selection. V to select whole lines. Ctrl-v or Ctrl-q to select a block (all rows having same width, forming a rectangle).
  2. Move the cursor.
  3. d (delete) to cut, or y (yank) to copy.
  4. Move the cursor to the desired paste location.
  5. p to paste after the cursor, or P to paste before (wcf note: then I should use P according to my habit).
  6. If you want to change the selected text, press c instead of d or y, it will delete the selected text and enter insert mode so you can type the new text.
  7. Instead of inserting the block, it is also possible to replace (paste over) the destination. To do this, move to the target location then press 1vp (1v selects an area equal to the original, and p pastes over it).
  8. o will move the cursor to the opposite end of the selection. O allowing you to position the cursor in any of the four corners.
  9. gv in Normal mode to restore your previous selection.
  10. It's really worth it to check out the register functionality in Vim: :help registers.

gvim, vim vs vi


Vim's added features include syntax highlighting, a comprehensive help system, native scripting (vimscript), a visual mode for text selection, and comparison of files (vimdiff).

gvim is built with GTK/X support.

Line number

To show the line number column, use :set number. By default absolute line numbers are shown, relative numbers can be enabled with :set relativenumber.

Jumping to a specific line is possible with :line number or line number gg. Jumps are remembered in a jump list, see :h jump-motions for details.
