What is the shortcut for copying everything?

Answer 1

For text,

You can use ctrl+A to select all , ctrl+C to copy and ctrl+V to paste it.

For folders or files,

You can use ctrl key and click the desired folders for alternate selection.

You can use shift key and click the starting folder and the ending folder to select the folders between those folders.

For example

These are the folders you want to select :

A

B

C

D

E

I will use ctrl key and click A, C and E to select only those folders.

I will use shift key and click A and then E to select A,B,C,D and E (all the folders).

I hope its clear for you !!
