Here I will post some usefull vim shortcuts/commands that I often use(and forget) for those of you that care.

Comment out multiple lines

• Go to the first line you want to comment out
• Press CTRL + V to enter visual block mode
• Mark the lines you want to comment out with Up or Down
• Hit SHIFT + i to enter insert mode
• Type in the character you want to insert the comment with. eg. #
• Press ESC and vim will fill out every line with the character of your choice.

Remove whitespace
