You can choose different ways of seeing the data, and a whole set of choices as to what columns you want to display for each new concordance. You can re-instate any later if you wish by changing the Layout.
Some of the options are visible here:
Blanking = blank the search-word out e.g. to make a guess-the-word exercise
Padding = insert a space to left and right of the search-word so it stands out better
Tag List (colours): a window offering a chance to switch colours on and off.
hide undefined tags = hide those not defined in your tag file
hide tag file tags = hide all tags including undefined ones
words coloured = colour words
tags coloured = colour the tags
hide the sentence tags = hides e.g. <s> and </s> tags.
hide the paragraph tags
hide heading tags
hide section tags
