A question asking how to accomplish a task with some specific software, as opposed to looking for some software to accomplish that task, would be off-topic. Such questions would typically be on-topic for [Super User](http://superuser.com/) for end-user software and for [Stack Overflow](http://stackoverflow.com/) for programming questions.

It may happen, sometimes, that the asker already has the software that they need but don't know it, as in your [SciTE](http://softwarerecs.stackexchange.com/questions/4254/autoit-ide-with-customizable-code-editor-font) example. If that's the case, then so be it. “You don't need any third-party software for this task” is a valid, if rare, answer here.
