Bug Description

Mesh segments can be set to be straight from the default curved one any time, even after new nodes are added but selecting two neighboring nodes and clicking the make curved segment icon doesn't do anything.

On a side note the node tool can edit the mesh nodes and handles but its make segments linear/curved option doesn't work either.

Tested on win 10 64bit Inkscape 0.92pre3 15195.

Also, mesh segments cannot be dragged as the node tool can drag path segments.

Please read the tooltips of the two icons on the meshtool controls bar:
The one with the straight line symbol is a _toggle_ action to extract / retract mesh gradient node handles.
The one with the arc symbol will attempt to smooth a curved segment to approximate an elliptical arc (this requires that node handles are already extracted and form a curve similar to an arc or ellipse segment).

Tavmjong used it to track issues and requests fixed/implemented in November/December (between the two release candidates 0.92RC3 and 0.92RC4).

Sorry I missed the tooltip, icons were confusing.
Alt+B works as well, thank's for the information!
Although that combination is used for creating a bitmap copy as well.

Remaining problem, when you toggle a segment from linear to curved or vice-versa, the mesh nodes are deselected and you need to select them again one by one.

Not sure what's the key combination to make a segment linear, but let's say you have a segment with random handles that you want to edit "from the start" and switch it to linear after selecting its end nodes.
After that, pressing Alt+B and instead of a curved segment you end up with inkscape hanging for seconds making a bitmap copy (had set its resolution to 600 dpi before).

Oh I see it's already fixed in the link.
