The command CHANNELS list all channels which are currently open (including channels from any other job) to the given channel (default #1).
Each channel is listed with a channel number which can be used with CLOSE% and provides details of its size and position. Unfortunately, the name of the Job which owns the channel is not listed.
The Tiny Toolkit and Qsound version of this command do not currently work with the Pointer Environment. The BTool version works to some extent.
