I often reuse code from other screens or that are otherwise organized.
I think of copying in a sequence that will always be added underneath the existing text in the clipboard, so with just a CTRL + V paste all the code and adjusting only what is necessary.
Ex:
CTRL + C opens a new clipboard.
CTRL + SHIFT + C increments the current clipboard by adding the copied text below the current clipboard.
Ex:
CTRL + C = CLIPBOARD = "Dim SSS as String"
CTRL + SHIFT + C = CLIPBOART = "Dim SS AS String *
Dim B AS Double "
