In the regular DOS command prompt, I can hit Ctrl-C to stop an operation in its tracks. So, let's say I run a long operation in a loop, iterating over all subdirectories, like this: for /d /r %G in ("*") do [command] %G with the regular command prompt, I can stop it at any time with Ctrl-C. However, I can't find any way to do so in TCC. To be sure, there is an option to support Ctrl-C in batch files, but that doesn't seem to help here (perhaps because this is not a batch file with multiple lines, but rather a single line command). As far as I can tell, the only thing I can do to stop it is to close the TCC window altogether - not a great solution because I lose all my history!
