When working on R source files I am unable to enter dollar signs in column editing mode. When I select a column and type $, only one is entered in the first line and the column mode is left. This happens regardless of width of selection.
On my system I can replicate this by creating a new R file consisting of
foo_bar foo_bar
selecting the column with the underscore and typing $
which yields:
foo$bar foobar
with the caret after the $.
Oddly this doesn't occur if I type another character before typing the dollar sign.
TIA
