I have been playing around with the editor and the Help on the current function.
Ctrl+H operates reasonably well but the behaviour can be slightly strange

In the examples that follow, | indicates the position of the caret.

So with 

aggregate(d|f[.....

Pressing Ctrl+H will give the help page for aggregate.

However in this case

aggre|gate(df[...

the word aggregate is entered in the Help search field. 

And in this case

getOption("verbose")
suppressPackageStartupMessages(library(doBy))
summ|aryBy(height + weight + age ~ sample, data = df, FUN = mean)

with the caret within summaryBy I got help for options.
But if the caret is in the word "library" I'll get the help page for message.

I expected that Ctrl+H would first try to get help for the current word containing the caret/cursor just as it does in TextMate using the R bundle. And if that fails looks backwards.
