Lately, TeXstudio made changes to how macros and their shortcuts are handled. Before the change, macros were defined in the macros menu, and then shortcuts could be assigned under Options > Configure TeXstudio > Shortcuts. Now, one can assign shortcuts directly in the macros menu, and also export and import macro files from the same menu.
When I click on Export, I choose a folder and save the file, but when I try to import, no macro files are recognized. From the menu it seems the expected extension is
.txs, but it doesn't work. What is the correct file extension to be used for macro files?
