Is it possible to have a 3 pane layout, such that I have three columns in RStudio? Most left editor, middle editor and right console?
Furthermore, how do I switch between editor tabs? It'd be great to be able to do the command+1,+2, etc. trick. CTRL+1,+2 works for editor vs. console
I don't know about multiple open editor tabs. But you can switch between editor tabs (assuming they are in the same window) with Ctrl + Tab to move right and Ctrl + Shift + Tab to move to the left
Ctrl + Tab
Ctrl + Shift + Tab
There isn't any three pane option, but one popular option is to open your .r or rmarkdown files in a new window.
