Select this 'Skills' tab to access the characters skills tree, and use the scroll bar at the bottom of the page to view all the choices available. The default view is the 'Details' page, which has a 'Skills' tab directly next to it.
The skill selection sheet is accessed by selecting the second of two tabs that appear when you select to see a characters details from the campaign map.
Additionally, there is a limitation to the amount of skill points that will be made available to each character such that careful consideration of the benefits and necessary unlocks required for certain skills should be taken into account when planning out the development of a character. In almost all instances of skill development there is an 'unlock' mechanism that limits the selection of skills based on the amount of experience a character has obtained and on previous skill choice, such that prerequisite 'key' skills must be selected before others will be made available for selection.
