When using multiple cursors for structural editing of org mode trees: org-metadown, org-metaleft and org-metaright function for all cursors, but org-metaup has no effect.
For example, if I have four headings, put cursors on the middle two, then M-<up> results in no change, whereas M-<down> results in the second and third headings moving down to positions three and four, i.e. M-<down> turns...
meta-up, meta-down, meta-left and meta-right are all in .mc-lists.el under (setq mc/cmds-to-run-for-all...). None of these commands are present elsewhere in multiple-cursors-core.el: neither in mc--default-cmds-to-run-for-all, nor mc--default-cmds-to-run-once.
I've tried removing the commands from .mc-lists.el and having multiple cursors add them back to .mc-list.el the next time I used the commands, but the errant behaviour of org-metaup persisted.
How can I fix this?
