This set of Alignment Scripts is one that I use most often for my personal use.

Each script runs a series of actions based on the selected object(s).

Read below for details on exactly how each script works.

Assign a keyboard shortcut to each script to quickly align a single object to the page, or multiple selected objects to each other!

byLFC_align bottom edges.jsx (I use Shift+B)
1) with ONE object selected, align it to the bottom margin of the page;
2) with TWO OR MORE objects in the selection, align them to the lowest point in the selection;
3) with TWO OR MORE WITH KEY OBJECT, align them to the lowest point of the key object in the selection.

byLFC_align distribute horizontal spaces.jsx (I use Shift+Alt+H)
Distribute the selected objects in the page, keeping the horizontal spaces the same.

byLFC_align distribute vertical spaces.jsx (I use Shift+Alt+V)
Distribute the selected objects in the page, keeping the vertical spaces the same.

byLFC_align horizontal centers.jsx (I use Shift+C)
Align the selected objects to its the horizontal center.
1) with ONE object selected, align it to the horizontal center of the page;
2) with TWO OR MORE objects in the selection, align them to the horizontal center in the selection;
3) with TWO OR MORE WITH KEY OBJECT, align them to the horizontal center of the key object in the selection.

byLFC_align horizontal left edges.jsx (I use Shift+L)
1) with ONE object selected, align it to the left margin of the page;
2) with TWO OR MORE objects in the selection, align them to the leftmost point in the selection;
3) with TWO OR MORE WITH KEY OBJECT, align them to the leftmost point of the key object in the selection.

byLFC_align horizontal right edges.jsx (I use Shift+R)
1) with ONE object selected, align it to the right margin of the page;
2) with TWO OR MORE objects in the selection, align them to the rightmost point in the selection;
3) with TWO OR MORE WITH KEY OBJECT, align them to the rightmost point of the key object in the selection.

byLFC_align top edges.jsx (I use Shift+T)
1) with ONE object selected, align it to the top margin of the page;
2) with TWO OR MORE objects in the selection, align them to the highest point in the selection;
3) with TWO OR MORE WITH KEY OBJECT, align them to the highest point of the key object in the selection.

byLFC_align vertical centers.jsx (I use Shift+V)
Align the selected objects to its the vertical center.
1) with ONE object selected, align it to the verticalcenter of the page;
2) with TWO OR MORE objects in the selection, align them to the vertical center in the selection;
3) with TWO OR MORE WITH KEY OBJECT, align them to the vertical center of the key object in the selection.

byLFC_align toggle alignment target.jsx
Toggle the application alignment target between selection, margins, page, spread (and key object, if there is).

The HIDDEN GEM to this combo is TO CREATE KEYBOARD SHORTCUTS.

See Profe Ivan’s video showing how he uses this combo of scripts. It’s awesome to see it in real-world scenario.
