When jumping to a member declaration or definition with one of Ebrowse's commands, the position from where you performed the jump and the position where you jumped to are recorded in a position stack. There are several ways in which you can quickly move to positions in the stack:
The stack is not popped, i.e. you can always switch back
and forth between positions in the stack. To avoid letting
the stack grow to infinite size there is a maximum number of
positions defined. When this number is reached, older
positions are discarded when new positions are pushed on the
stack.
