Within Vim do the following:

• Move cursor to the first starting line where you want to start editing
• ctrl + v to enter select mode to select all characters in one column
• Move the cursor vertically down until you selected the last line
• shift + i to got into "multiple" insert mode
• Do all the required editings
• Use the ESC-character exit insert mode
• Press ESC-character to apply all changes

Hint

This does not work with deleting and editing at once

• If you first want to delete the content, can also use the select mode of ctrl + v to select the content to delete
• Delete the selected box by pressing d
