Selection.

It does not work when SL tool is ON only when it is OFF and viewport SL tool is OFF, that is why I asked for KeyLess selection Tool. Or I miss something?

There is no way it can work when Viewport SL tool is On.

You can create a streamline tool to hold the selection tools so you can access those selection tools through the streamline tool.

It can work with Replace, Include, Exclude Selection but can not work with Include/Exclude selection (KeyLess Selection)?
My logic is that we have to create new tool - Include/Exclude Selection.
It will temporally enable selection mode and allow us to do our things like it is now with for example Include Selection.

OR, If Use keyless contextual selection operator is ON - Replace Selection will work like KeyLess selection(Automatically Include/Exclude Selection).
So if SL tool is Activated and you run Replace Selection it will allow you to Include selection if subobject is unselected or Exclude selection if subobject is already selected.
I think it is how it should be!
KeyLess selection is great feature!

Absolutely crazy stuff!! Many thanks!!!!!

3. Now selection works like:

Selection:

LMB
Without/With Selection Keys - Paint selection

MMB
Without Selection Keys - it is free.
With Selection Keys it works as Simple Click selection. Disable it Pleas! (If we have Paint selection(LMB) we do not need this) We need it to make Gap/Range selection, so leave it as it is.

RMB
Without Selection Keys - Simple Click selection. Disable it Pleas! (If we have Paint selection(LMB) we do not need it.
With Selection Keys -  It is free.

Style Selection:

LMB
With Selection Keys - Simple Rectangle Selection (Works only if you start drag from empty space) Disable it Pleas!

RMB
With Selection Keys - Rectangle Selection Through. Works nice!

RMB
With Selection Keys - Is free. Add pleas to it Simple rectangle selection(Not through).

I found it's hard to understand this. There is no RMB for selection in current Nvil behavior.

Good lets look at it from this point.
I'm offer just simple shortcut optimization.

If we have - Switch paint selection from MMB to LMB set to ON.
Simple Rectangle Selection(Not through) works with LMB drag.
It works only if you start drag from empty space. We can not activate it if cursor is above subobject/object, because it will activate paint selection.
I offer to disable it and move to RMB(drag). RMB(drag) is free and it will allow us to start it not only from empty space but everytime we launch it, no metter if cursor is in empty space or above subobject/object. So if you RMB drag it NVil will perform simple Rectangle selection.


Let me know if you need additional information.

 * Edit > Customize > Tools > Common Modeling Tools > Marquee Selection/Marquee Selection(Through). It is used to set the mouse button for marquee selection. This option is removed, Edit > Preference > Options > Switch marquee select through from MMB to LMB.

8. I just leave it. Too complicated.

11. Done.

Great, Many thanks!
I know I'm torturing you but pleas excuse me, I just want to make things perfect. There are some last little steps about Selection we must to finish.

1. Marquee Selection, Loop Selection, Ring Selection, LMB+RMB to switch objects from Sub Object Mode, Pattern Selection have to work in Contextual Mode selection if you run it with with Contextual Selection key or if you have Use keyless contextual selection operator ON. Now only Paint selection works with Contextual Selection.

2. Need to think about it a bit more.
To make SL tools works smooth with buttons we have to make some simple rules.
So when you change Selection Mode:
- If active SL tool is Generic tool, it will be never dropped.
- If active SL tool is Sub Object tool, it will be dropped only when you switch to object Mode.
- If active SL tool is Spline/Vertex/Edge/Poly/Object it will be dropped everytime you switch Selection Mode.

For this we will need this tool - Contextual StreamLine tool Cancel. So I could put it composite tools that switch Mods.

3. If you have Multi Selectio ON, during deselection of polygons NVil keep edges selected. Check this video:

Great, Many thanks!

Now only Paint selection works with Contextual Selection.

I think it works with marquee selection already.

Marquee selection with Contextual Selection:

Do not work when (tested with polygons):
- When you Start select from empty Space. (It works like replace Selection but have to work like Contextaul Selection*)
- If you start select being above subobject but selected nothing. It will just drop Selection. But NVil have to do nothing in this situation.

*Also,

Now:
If you start select from selected Subobject everything inside Marquee  will be Excluded from selection.
If you start select from unselected Subobject everything inside Marquee will be Included into selection.

Have to be:
If there are Selected Subobjects inside Marquee they will be deselected.
If there are Deselected Subobjects inside Marquee they will be selected.

Now:
If you start select from selected Subobject everything inside Marquee  will be Excluded from selection.
If you start select from unselected Subobject everything inside Marquee will be Included into selection.

Have to be:
If there are Selected Subobjects inside Marquee they will be deselected.
If there are Deselected Subobjects inside Marquee they will be selected.

What is "Deselected Subobjects" ?

What is "they"? All the subobjects inside Marquee?

What is "Deselected Subobjects" ?

Subobjects that is not selected.

What is "they"? All the subobjects inside Marquee?

So If you have this Marquee Selection(red line):


After you releas Mouse button selection will look like this:


All subobjects that was selected become unselected and all subobjects that was not selected become selected.

So it is toggle selection. Right?

Marquee selection with Contextual Selection:

- If you start select being above subobject but selected nothing. It will just drop Selection. But NVil have to do nothing in this situation.

Some people use this to clear selection when using tablets. So I am not going to change it. It is not worth to create an option either.
