Option to show tooltips only when modifier is held

[eugenesvk]

I find settings.tooltip by default to be more annoying than useful when editing a config as it interferes with regular mouse navigation, so I disable it.
However, sometimes it's very welcome indeed! Is there a way to configure it to only show if I hover with e.g. Shift key pressed?

Unfortunately, it is not possible within the ST API to request the currently held modifier key for on_hover hooks or on demand. Such functionality generally exists (see docs, but only for command invocations triggered by a mouse interaction (defined in a .sublime-mousemap file), input handlers and quick panels.

I could try to interact with the respective platform's API to determine whether a modified key is currently held, but this is not something I am willing to implement.
