Sorry that this is such a simple question, but the Maxima manual doesn't appear to have an answer to this.
I recently upgraded from the 5.16.x series (Windows/XP) to the 5.18 (via 5.17). I noticed that the input command window no longer appears as was the case in 5.16.x. Instead, there is a red marker that expands as you enter <CR><LF>. I assume this is a new command entry method? If I simply enter "integrate(cos(x),x);<CR><LF>", for example, how does one terminate the input and have Maxima execute?
I know, this is dumb, but it is not clear to me what the use case is.
Thanks,
Dave
