**Merge the currently selected nodes into one node.**

**Note**: There is also a merge nodes function associated with the [Action/Select Select Move tool (you have to hold "Ctrl" while moving object)].

== Merge conflict ==

If user joins two nodes with same key, he will be prompted with dialogue to select one of 4+ desired values (''in illustration below two points with tags note="3" and note="4" were merged''):

* 3 - note=3 will be left
* 4 - note=4 will be left
* (more values will appear here) - (same as above)
* none - note= tag will be removed
* all - note=3;4 will be left (or note=3;4;5 or more values will be glued until 255 limitation in value will be reached)

== Can't merge because way still in use == #WaysToDeleteStillInUse

The nodes you merge may be part of [Concepts/Object#Ways ways]. If you merge them these "parent" ways may loose one or more of their nodes. In some cases the number of nodes left in these ways may drop below 2. Ways with less than 2 nodes don't make sense and JOSM tries to delete them.

In some cases, though, a way to be deleted could still be in use, for instance, because a relation is referring to it. JOSM aborts merging nodes in these cases. Instead, it displays the following warning message: 

[[Image(warning-way-still-in-use.png)]]

Click on ''Abort Merging'' to close the dialog. The selected nodes are not merged.
