It depends on what you mean by "trigger". Triggered by the mouse, I think you're right. But see the attached patch. Since [del] (among other objects, but I used [del] here for clarity) can schedule bangs between boundaries, you can trigger [vline~] in the middle of blocks. Not so with [line~]: if a bang is scheduled in that block, it starts the ramp at the beginning of that block and ends it at the end of a future block such that the total ms of the ramp does not exceed the requested ms.
