You do not mean the "enter" key: it is not that which exits the 
browser but rather a newline (which can be entered via 'return', and 
in other ways).

This is part of the parser, and there is no way to turn it off.

Somehow other experienced R users have never encountered this.  But if 
you wish you could submit this as a 'wishlist' request to R-bugs, and 
if enough users support it (and especially if someone submits a 
high-quality patch to do this), it might be added in a future release.

Dear R,

How can I disable using "enter" key to exit the browser() in debug mode? I
would love to have this option because it is so annoying to jump out of the
debugging mode unexpectedly when I don't want to. I guess some of us have
encouraged at least one of these situations,

1, Accidentally pressed the enter key within the browser.

2, Copy and paste a piece of debugging code containing empty lines to the
prompt within the debugging mode.

3, If I paste a piece of code to the prompt to debug as follows, it will
eventually jump out before I can do anything.

####### copy starting from this line ##############
test <- function()
{
    x<- 5
    browser()
    y<-4
}

test()

######## end of copy at this line ################

Any suggestions are most welcome!
