There might be some tutorials on this, but I'll just try to cover the most important tools for blending two motion clips: "Align" tool and extendable "Blending" portion of the second clip.
First you want to space 2 clips and slide blending portion of the second clip to the end of first.
"Align" is where you right mouse click on the second clip and use Align tool to align character to the selected limb.
In other words selected limb at the beginning of the second clip assumes the coordinates of that limb from the last frame of the first clip without disturbing overall pose.
In most of the cases you would want to align to one of the legs. Smooth transition for limbs other than legs is taken care by Blending portion of the second clip (it should be long enough).
But legs would most likely slide along the ground in transition. That is why securing at least one of the legs is crucial.
So once you aligned second clip to right or left leg, you might need to create a proper transition for other leg (it might still be sliding) and/or for other limbs.
To do that, you'd have to create a key at the end of the first and at the beginning of the second clip and merge 2 clips.
Now the space between 2 keys is your Blending motion. In between those 2 keys you can do whatever it takes to smooth motion further.
Like create a small step for the other leg to overcome sliding and possibly do some minor tweaking of the other parts.
