[TxMt] Column selection question

[Timothy Bates]

Hi there,

Taking a dummy example string like:

KIBRA
C/T
T/T
C/C

Questions
1/ Using the keyboard, how do I make a zero-width column selection at the
last position for each of the bottom three lines? The manual suggests that
holding option-shift while moving (arrow) from the top to the bottom lines
should do it, but this doesn't create the right selection for me, and when I
push option, the selection is not converted to a zero-width column cursor
(nothing happens).
 
2. Can I type at the end of each line (given that the lines end on different
columns)?
