In InDesign, you do pretty much the same thing but first select the type tool, make a narrow & deep text block. Then type a letter, return, type next letter until you're done. You can just touch the type box with the blak arrow to globally change the font, leading, type size, centering, etc. If you have too many letters for the size of the box, a little "+" sign will appear in the lower right corner - take the black arrow & drag the box deeper until everything appears.
