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.
