You can't directly select edges in the graph pane, but you can select them in the workbook. Actually, you mentioned two problems, one involving vertices and one involving edges. In the first example below I assume you have an undirected graph,
in which case degree is the relevant graph metric.
To select all vertices (and their incident edges) whose degree is greater than 2:
1. Use NodeXL, Analysis, Graph Metrics to calculate degree. This adds a Degree column to the Vertices worksheet.
2. Select the Vertices worksheet by clicking the Vertices tab at the lower-left corner of the Excel window.
3. Sort the Vertices worksheet by clicking the down-arrow to the right of the word Degree and selecting Sort Smallest to Largest.
4. Click the first cell in the Degree column with a value of 3 or greater.
5. Press Ctrl-Shift-DownArrow to select that row and all that follow.
To select all edges (and their adjacent vertices) whose edge weight is 5 or greater:
1. If you don't already have an Edge Weight column on the Edges worksheet, use NodeXL, Data, Prepare Data, Merge Duplicate Edges to merge duplicate edges and create an Edge Weight column.
2. Sort the Edges worksheet by clicking the down-arrow to the right of the words Edge Weight and selecting Sort Smallest to Largest.
3. Click the first cell in the Edge Weight column with a value of 5 or greater.
4. Press Ctrl-Shift-DownArrow to select that row and all that follow.
