LinkHints.activateOpenUrl, background and queue

[anglimath]

The objective:

map xxx for the following purpose,
Open multiple urls in background tabs without simulating the click (in a queue).

I know one possible way to achieve this is

1. map xxx LinkHints.activateOpenUrl reuse="new-bg",
2. press alt to change to queue mode. (Message: Open multiple URLs directly)

However, how can I use a single key to achieve this? (not simulating a sequence of keys)

I have tested all possible combinations of the followings, none works exactly as expected
LinkHints.activateOpenUrl
LinkHints.activateWithQueue
mode="open-direct"
mode="queue"
reuse="new-bg"
mode="cur-queue"
...

Could you please give me some hints? Many thanks!

Also tried active=false, which doesn't work neither. To make the question description more accurate, the message would be (Message: Open multiple URLs directly), because this is the only way to make it work on "zhihu.com".

You may try:

map xxx LinkHints.activateOpenUrl reuse="new-bg" mode=62

But the usage of mode=<number> is not recommended, because the number may changes when I think it's necessary...

I'll add a new way to achieve this effect using mode=<string>.

Thanks! It works.
