If you're using an editor like Vim, the bookmarks and registers you've created remain alive only as long as you are editing. When you save/close the tiddler, all that work is lost. But if you don't save, then the changes you've made (for instance, to macros) won't be available.
Has anyone developed a method so that you can save the contents of an edited tiddler to the source (unopened) tiddler without closing the current edited tiddler?
Thanks!
