to select on the timeline

[lapasoa 111]

When i'm tweaking  some clips of a track and I click selecting  them on the timeline, as I finish clicking all the tracks are selected.

It's very annoying.

Try using the select "from now to now" under editing. That will give you your desired time frame. Then click the tab for each track, way over on the left. That will select just the tracks you want.

Edit: you may need to do it in reverse - first select the tracks with the tab on the left, then set your time frame.
