Select multiple messages using ctrl / cmd key

[g105b]

Shift key works as expected in OS; click one mail in the list, shift-click another, and all mails in between are also selected.

Control/Command key should toggle selection of individual messages per click.

This issue appears to be platform-specific. On the Mac, cmd-clicking threads selects them individually. It seems we forgot to make this work on Windows / Linux. I'm not sure what the desired behavior is on Windows—in Windows Explorer, it looks like you have to ctrl-option-click to extend your selection. @g105b do you have any thoughts what the correct behavior should be?

My platform is Ubuntu Linux, I haven't tested on Windows.

The expected behaviour is to toggle the selected status of each clicked element while Ctrl is held, with no context to other selected elements.

Can't use ctrl key on Windows either. Shift key works but when I need to add another mail from X rows below to the selection, it doesn't work.

Same for me on Ubuntu. I can't use ctrl key to select multiple threads. Shift key works perfectly

I would like to also confirm this issue.... Ctrl behavior does not work as expected, shift key works as expected.

I'm tagging this as a good starter issue. Technically, we already support the behavior being described here. For some reason, the logic in this function is not working as you'd expect on Linux: https://github.com/nylas/N1/blob/unified-inbox/src/components/multiselect-list.cjsx#L140.

It looks like event.metaKey might not be the correct think to check for on Linux?

[g105b]

I can confirm that in Linux, multiple emails can be selected using the super key, instead of the ctrl key, as expected.

Might have a look at fixing this one myself later.

The Event object has a ctrlKey property, I think this should be standard on all platforms but in case I put it after the or operator as to not affect existing behaviour.
