Tiled is a very good editor and I'm enjoying using it. Thanks for your great work!
Right now Tiled has, according to the wiki, one key, F5, that one can press and run a command. It can get a bit inconvenient, when one has two or more commands that are used frequently ('test map' & 'edit teleport target map', for example).
Supporting fully customizable shortcuts would be of course a lot of work, and probably overkill, but a few extra keys, like F6 and/or F7, could be very useful, and does not seem to be too hard to implement. What do you think?
