v will select the same number of characters as the previous selection, but starting from the current cursor (see full help below). When there was no previous selection, it will select
count characters. Is it possible to reset this count to obtain the default behaviour?
[count]v Start Visual mode per character. With [count] select the same number of characters or lines as used for the last Visual operation, but at the current cursor position, multiplied by [count]. When the previous Visual operation was on a block both the width and height of the block are multiplied by [count]. When there was no previous Visual operation [count] characters are selected. This is like moving the cursor right N * [count] characters. One less when 'selection' is not "exclusive".
