raise the level of automation curve?

I don't use a curve with lots of nodes in it. I opt to make linear envelope movements. Although it is possible to use a curve between 2 nodes.... I like the linear straight lines. Generally my lines are short fades so a curve is not needed. 

Of course you know you can grab between two nodes and move the level up or down, IDK, but with a multi-node envelope such as a written fader move, I'm thinking you might be able to lasso a number of nodes and move them as a group.... I would need to look that up though since I tend to have precise surgical envelope edits as seen below. I enter all my nodes manually. 

maybe not the best option, but I automate tracks and then send them to a bus so if I need to adjust overall volume I can, however this only works with volume.

You can always apply a clip gain envelope. Note that this is may be impractical if there is a compressor in the track fx bin, as the clip gain is applied pre-fx and will affect the compressor's sensitivity.

I am more likely to simply grab all the automation nodes and move them up or down as a group. 

Another comment on clip gain envelopes while I'm at it: if you use automation for de-essing and taming resonances and such, be sure to use a clip gain envelope rather than a track volume envelope. It'll make your compressor work less hard, allowing gentler ratios on your vocal tracks.

Hey, lawajava - 81 degrees today here at my place. Pretty all right, eh? All day I was humming "hot town, summer in the city...".

Do you mean you'd like to raise the entire envelope? If so, while editing automation, hover your mouse near the top of the clip. It will turn into a horizontal I with two arrows pointing up/down. Then click/drag up/down to raise/lower the entire envelope.

Wow lots of ideas. Yes i meant raise the level of the entire clip, maintaining the ups & downs of the automation curve.

This is hugely exaggerated and on the wrong colour background, but you should get the general idea:

I know some people don't care for it, but I find Offset Mode to be the simplest way to make an overall change to a control that already has automation assigned.   Type "O", see a "+" added to the control, make your change, then type "O" again.     Easy peasy.   YMMV and all that.  

Much easier than trying to make that smart tool change shapes.

 
Hehehe...  yup.  
 
I do frequently use the "hover over the top" technique to modify envelopes after selecting ranges, because I usually (but not always) find it easier than manually adding nodes.   But for overall changes I prefer to use something simpler that requires no manual dexterity or accuracy.
