How to delete all lines of file in Vim

Problem

To delete all the lines of a file that is open in Vim.

Solution

• Type gg to move the cursor to the first line of the file, if it is not already there.

• Type dG to delete all the lines.

Deleting all the lines of a file is not a frequently used operation. So, I need a command that is easy to recall, even though it is not used much. I find dG easy to remember since I frequently use dd to delete a line, and also gg and G, which move the cursor to the first and last line of the file respectively.

Tried with: Vim 7.3
