When the identifier is a letter or a complex number which has the
form "sector - ring - number", one should use the command
tab and the option -k.
Be careful about the structure of the complex identifier and the position of the white spaces.
This option may also be used to search for stars identified by letters.
However the search is not selective. Searching for A
will display all lines containing an A.
tab -k 32- 37 displays the line containing "32- 37"
