How can I set valid value to visual bell?

I want to get a visual bell in my mvim. I set :set vb to get the visual bell. However, the flash is not obvious because the flash duration is too short.

According to the help:

In the GUI, 't_vb' defaults to "|f", which inverts the display for 20 msec. If you want to use a different time, use "|40f", where 40 is the time in msec.

So the default 20 msec is short, I want to change it to a longer time.

My problem is I couldn't set the value of 't_vb' to a valid value:

  • I set by press Ctrl-V then Esc then |100f, vim complaint with "Invalid Argument"
  • I set like :set t_vb="<Esc>|100f", vim did not complain but it didn't work either.

How can I set the value for 't_vb' properly? Thanks!

Solution

  • You need to escape the |

    Like so:

    :set t_vb=^[\|100f

    (where ^[ is entered by using Ctrl-V followed by Esc.)
