I often preemptively match delimiters. As a simple example, I'll type
Import, then left arrow, then
The problem is that when I type the
[ highlights in the normal selection color to signify that this pair of brackets matches. During this automatic highlighting, if I type something that involves the shift key (such as something starting with
] is deleted, leaving
Import[". This behavior is as if the
] was selected when the
" was typed, but it was not.
To reiterate, the sequence of keys is (quickly typed!)
Import then Left Arrow and Shift+' but the behavior is as if the sequence were
Import and then Shift+Left Arrow and then Shift+'.
It might be my imagination, but it seems to have gotten worse in Mathematica version 9.
Can I disable or shorten the automatic highlighting of matching delimiters? It appears to be the source of the phantom shift keystroke.
This is Mathematica version 9 on Mac OS X 10.7.5.
Wolfram support suggested unchecking "Enable dynamic highlighting" and this does not fix the problem. I recorded the problem happening twice in a row here. It happens a bit faster than it is being displayed here.
I'd settle for just shortening the duration of this highlighting so I'd have to be Superman to reproduce the problem.
