Techslinger: What action is it to use the Charge Recycling deed?

[FiddlersGreen]

Charge Recycling (Ex) At 11th level, by spending 1 grit point, a techslinger can grant 1 temporary charge to a technological firearm, even if the firearm normally can no longer be recharged. This charge must be used within 1 hour or it fades. The techslinger can grant temporary charges to multiple firearms as long as she has enough grit, but temporary charges do not stack with themselves in the same firearm. At 15th level, the techslinger can grant 2 temporary charges when she uses this deed, and at 19th level, she can grant 3 temporary charges. This deed replaces expert loading.

Nifty ability, allows a Techslinger to shoot his tech firearms alot more regularly.

But what action is required to use this deed? Unlike most deeds, no action is specified for the use of this deed apart from the expenditure of the grit.

Interestingly, the deed that it replaces, expert loading, also does not specify any action for its use.

Any insights?

I believe that most abilities default to standard actions if no other action type is specified.

Is that in the CRB? I was trying to find something about this but could not find it there.
