Shortcut for executing several lines in RStudio

Question

I'm using RStudio and normally run my code line by line, using Crtl + Enter. In general this works fine but working dplyr I would like to run a whole code-section I wrote using the pipe-operator %>%,

For e.g. I'd like to execute the following code-section at once, at the best independently from the current cursor position within the piped codelines:

mtcars %>%
  filter(carb >= 2) %>%
  group_by(cyl) %>%
  summarise(mean.hp = mean(hp))

I could run this line by line or mark all lines and then press Crtl + Enter but both ways are some kind of annoying. Searching the internet and the RStudio-options available in "Tools/Modify Keyboard Shortcuts" I only found other options like running a whole section, that is starting at

# Example section--------------------

Answer 1

Place cursor anywhere in the code chunk and use Crtl + Shift + ↑ (hold down Crtl and Shift, then push ↑ button). The first time the word in which the cursor is placed gets highlighted, then, when repeted, the whole chunk of code gets highlighted. If you have a nested loop or another nested structure this will highlight the whole innermost loop, then the second inner most loop etc.

When you have the code highlighted you can press Crtl + Enter to execute the code.

Answer 2

I use the sections feature of RStudio liberally (like you noted) - but you didn't mention the keyboard shortcut Ctrl+Alt+T to run the section (all the code between # comment ---- or #### partitions).

# mutate ----

# rename ####

# filter ####

# summarize ####
