What are these?

The dotted lines I mean. When I autoslice a file in Edison it creates markers but if I drag it into Reaper the markers get converted into these dotted lines - not Reaper markers or slices. While it's an advance on most other audio apps that don't even seem to support drag and drop from Edison I can't seem to do much with them - surely it would be best if after auto slicing it was slices it exported?

cues, afaik which i think you can perform a slice on cues action? or something?

Cues? I can't even find them on the Reaper menu. What do I do with them to convert them into proper slices? There doesn't even seem to be any way to grab them or move them with the mouse.

Great I've found an action to split at cues which works nicely. But I wish this wasn't so hidden away - is there any way to move/edit cues?

I can't even see how they get there in the first place (OK I see they come from Edison's markers but how do you make them in Reaper?)

Those lines look like dynamic split lines.

Item Cues FTW! :) (Reaper can insert em, by Render Markers as Cues)
