R Studio keyboard shortcuts

When you code a lot in R it is nice to work with the keyboard. There are some commands and code you will repeat again and again and it is useful to know that there are shortcuts for certain code and commands. R studio has made a whole list of shortcuts: rstudio-IDE-cheatsheet. Here a small selection of what I have found useful:

Mac Windows
Move cursor to start of line Cmd+< home
Move cursor to end of line Cmd+> end
Change working directory Ctrl+Shift+H Ctrl+Shift+H
Select to line start/end Cmd+Shift+</> Ctrl+Shift+</>
Insert <- Option+- Alt+-
Insert %>% Cmd+Shift+M Ctrl+Shift+M
Copy line up/down Cmd+Option+▴▾ Shift+Alt+▴▾
