How do I ctrl-z undo in Alteryx?

[nyck3333]

Doing challenge 300 and just pressed down arrow in the join window and now left became right when it was supposed to be left and I want to change it back to left but don't know how.  Why can't I ctrl-z or just click the box and edit?

right is solution, left is mine

@nyck3333 If you click off of the tool onto the canvas, then press Ctrl-Z, the tool will revert to its previous state. Otherwise, to re-order the fields in the join tool you can select the country name field (so it appears blue) and press the 'Up' arrow next to 'Options' until it is at the top. Hope this helps!

Hey @nyck3333,

You can use ctrl-z, but only for everything done in a tool at a time. Once you click out of the configuration window, the actual information of your config. is saved, this can be removed again with ctrl-z.
