title: How to force the display the "Resolve Tool" dialog in TortoiseHg 2.x?
body: <p>(I've done this before, and I have no idea how -- it was by luck I found it then, and I cannot for the life of me duplicate the behavior. I think it was context-specific, somehow.)</p>
  
  <p><a href="http://tortoisehg.bitbucket.io/manual/2.0/whatsnew.html" rel="nofollow noreferrer">TortoiseHg 2.x</a> adds a new "Resolve Tool" <em>Dialog</em> which displays a list of files that needs merging and allows selecting a tool per file so that each can be resolved as appropriate. (I've <em>seen</em> it before.)</p>
  
  <blockquote>
    <p>TortoiseHg 2.0 introduces a resolve dialog ... It shows the users all the files that require resolution <em>and those files that have been resolved</em>, allowing merges to be verified</p>
  </blockquote>
  
  <p><em>How can I get this dialog to appear on a merge that otherwise "automatically" merges?</em></p>
  
  <p>Thanks.</p>

  <p>The "<em>real</em>" issue is that I am trying to merge A->B. There was a merge from B->A where changes from A were incorrectly taken, instead of those from B. (This changeset has since been pushed.) Now it's not possible to merge B->A again because B is an ancestor of A. When I try to do a "reverse merge" (A->B) everything "automatically merges" even though there are <em>incorrect</em> semantic differences. The new "Resolve Tool" dialog should allow me to override the automatic merging, but I <em>can't get it to appear</em>.</p>
  
  <p>I could get the equivalent by merging and copying/fixing the merged files by hand. I am looking for a way to do this nicely inside TortoiseHg itself where I can select "mine", "theirs", etc. Or perhaps a backout would be more appropriate? I tried that and just ran into more issues, as I still couldn't merge B->A again, which might be [another] PEBKAC...</p>
  
  <p>Additionally, I have set the settings "Three-way Merge Tool = internal:dump" and "Auto-resolve merges = false" to no avail...</p>

  <p>My "solution", which feels so hackish and unorthodox to Hg, was to force a branch and then "Visual Diff..." and merge over the changes I wanted (with KDiff3). In <em>this</em> context -- but <em>not</em> after an automatic merge, which seemed to leave orphaned merge files -- the changes from the merge tool were correctly applied to the WC. It still, however, fails to address my question: how/when is the "Resolve Tool" Dialog shown? It seems too handy to not be readily available.</p>
