I've some questions while progressing

[SavageMen]

I'm still in progress of the main story.

A way to get back to Novigrad or Velen from Skillege or Toussaint is only the fast travel ?

I mistakenly tabbed on Caps Lock key instead of Tab while fighting monsters, it has no function ? Nothing will happen ?

Am I able to replenish Swallow and Bombs without Meditation ?

 

[Nithing]

Fast travel is the only way to travel to different map areas (White Orchard, Velen/Novigrad, Skellige, etc.)

Caps doesn't do anything as default.

There is a way to replenish potions in Blood and Wine without meditating but not before then. Sometimes during important sequences (in the main game and DLC) going to meditate (the N key) will replenish your supplies without actually meditating.

 

[Hobbs1017]

you have to fast travel on the world map between those areas. and you can only replenish when meditate
