Separating chunks of code using commented line [closed]

Question

I would like to separate my code using commented line to make them more readable like below:

# ----------------- reading data -------------------
df = cars

# ----------------- data Summary -------------------
summary(df)

just wondering if such an approach is common among experts to add something like titles in their scripts and whether there is a shortcut key to produce such lines: ------------ instead of repeatedly tapping on the - key?

Answer 1

A cool thing with RStudio is that you can do navigable sections:

# reading data ####
df = cars

# data Summary ####
summary(df)

You have to start with # and to finish with at least 4 # (or maybe this works too with 4 identical symbols).
