FlameGraph: navigation through search results

[apangin]

Describe the feature

Use N / Shift+N keys to navigate over highligted frames.
If there are multiple matched (highlighted) frames within a single stack, traverse only the largest one.

• N traverses found frames from left to right;
• Shift+N traverses frames backward: from right to left.

Use Case

Search feature of the FlameGraph (Ctrl+F) highlights matched frames with pink color. However, if matched frames are tiny (like 0.1%) it's very hard to find them. The proposed functionality allows to zoom into the next highlighted frame regardless of its size.

Proposed Solution

This is re-implementation of #1030. Unlike the previously proposed solution, this approach traverses only bottommost frames.
