The helping hands for me were the shortcuts. I had to do a lot of typing, so not only did I need to copypaste quickly, but also think of a way that would come in handy with custom coding and editing too.
It might sound weird, but an extra help for me was to use speech-to-text extensions. Of course, the syntax,like the parenthesis and dot-commas, comment dashes and dollar signs, opening and closing quotes I had to put manually.
I enjoy using these simple yet very useful features in VSCode: Multi-Cursor editing, and Line Actions (Shift+Alt+DownArrow or Shift+Alt+UpArrow, Alt+UpArrow and Alt+DownArrow).
