How can I select an entire column in the attributes table in QGIS? Ideally I would like to do it using a keyboard shortcut. In a search around the net I cannot find a way to do it.
I don't think you can select a single column. If you want to export a single column for copying into Excel or something then you have a couple options. You could select the entire table, copy, paste it into a spreadsheet, and the delete the unwanted columns. Or you could right click on the layer in the table of contents and click Export > Save Features As, then set the format to MS Office Open XML Spreadsheet and deselect all the columns/fields that you do not want to export.
