There's more than block selection which is actually quite limiting in comparison with the other possibilities. What I do often (SublimeText, VSCode for instance) is select a token, select a bunch of occurrences of that over multiple lines, then start editing from there. So in the case of e.g. unaligned equal signs select the first one, Ctrl-D to select the equals sign on the next lines, then move cursor around word by word and edit. Or indeed start by creating multiple cursors at the front of a line and start from there. Etc.
