Console History & History pane
To refresh your knowledge on how to execute and format R code in R Studio, see the previous article in this series.
Everything that you passed to the console doesn’t have to be typed again. Accessing previously executed lines is as easy as navigating with the up and down arrows to cycle between them in chronological order. If you want more visual feedback, you can press Ctrl + Up arrow to get a list of last commands. If you combine it with typing in a part of the searched phrase, you can narrow it down and easily find even complicated commands that are buried deep in the history. It will also override autocomplete popup if it’s active. Note: searching console history doesn’t support fuzzy matching, so you have to be exact. If you want to clear your console, use Ctrl+L, command history will be preserved.

There is also History pane(4) which stores executed commands. It allows searching. Easily select the ones you need (pick range with shift or gather individual positions with ctrl), then easily insert them back into the console (Enter) or source file (Shift + Enter). The latter helps you avoid copying multiple commands from console to source manually, which is troublesome due to line signs “>” that get copied along and would otherwise have to be removed.
Dealing with Tabs
If you find yourself working on more than one tab in source editor, you might find it helpful to switch between them with Ctrl+Tab and Ctrl+Shift+Tab combinations. It will allow you to jump to the next and previous tab, respectively. There is another way to do this with Ctrl + F11/ F12 if it suits you better. It is also possible to jump to the first or last one by adding Shift to those. Last option that is quite interesting is navigating through tabs in the order they were accessed with Ctrl + F9/F10.
Going through tabs back and forth

Closing a current tab is easy with Ctrl + w, it is a much better choice than using those small “x” buttons on the right side of your tabs.
If you get to the point where you have a huge amount of tabs open you can either:
Close All | Ctrl + Shift + w (+ Alt to keep currently open one),
if you prefer to keep them, you can search through your open tabs with Ctrl + Shift + . (be exact, no fuzzy matching here). This search can also be activated with “>>” icon on tabs bar.

Above shortcuts are also accessible from the File drop-down menu – this can get in handy while using R studio browser session or simply if you forget them.
