When working with Inkscape I have too open and close dialogs many times, like "fill & stroke", "align", "filters", etc. Althoug it is easy to open them with simple keyboard shortcuts, I haven't found the way to close them as fast. Could I assign shortcut to "q" key which would close currently active/selected dialog? Is it possible to set this shortcut in keys/defaults.xml file? If not, is there any external program that could do this? After short googling I have found Xbindkey, but I'm not sure if it will work it this case.

The shortcut for all the dialogues is Ctrl + W

A request has been reported to the bug tracker to use the same shortcut for opening and closing of the dialogues https://bugs.launchpad.net/inkscape/+bug/253775

What's the name of the action assigned to ctrl+w shrotcut which closes active dialog? Is it another hard-coded key binding?

I have found "FileClose" action assigned to "w" key in my default.xml file, but as its name suggests - it closes the whole program, not selected dialog:
<bind key="w" modifiers="Ctrl" action="FileClose" display="true"/>

The dialogue has to be selected (active) before you can use that shortcut, otherwise it closes the whole Inkscape window.

It makes sense in a way, since those are windows too only docked, but as you can see it can cause confusion, fixing that request would solve it all.

This seems to be hard-coded, I removed all shortcuts with "FileClose" action from /usr/share/inkscape/keys/default.xml, and I've set in my local ~/.inkscape/keys/default.xml:


Still ctrl+w closes dialogs (even if it's not declared in any default.xml file), and alt+f closes the whole program.
