| Tab or Shift+Tab | Move between screen elements, e.g. from the toolbars to the packet list to the packet detail. | Alt+→ or Option+→ | Move to the next packet in the selection history. |
| ↓ | Move to the next packet or detail item. | → | In the packet detail, opens the selected tree item. |
| ↑ | Move to the previous packet or detail item. | Shift+→ | In the packet detail, opens the selected tree item and all of its subtrees. |
| Ctrl+ ↓ or F8 | Move to the next packet, even if the packet list isn’t focused. | Ctrl+→ | In the packet detail, opens all tree items. |
| Ctrl+ ↑ or F7 | Move to the previous packet, even if the packet list isn’t focused. | Ctrl+← | In the packet detail, closes all tree items. |
| Ctrl+. | Move to the next packet of the conversation (TCP, UDP or IP). | Backspace | In the packet detail, jumps to the parent node. |
| Ctrl+, | Move to the previous packet of the conversation (TCP, UDP or IP). | Return or Enter | In the packet detail, toggles the selected tree item. |
Common Filtering Commands link
| Usage | Filter syntax |
|---|
| Wireshark Filter by IP | ip.addr == 10.10.50.1 |
| Filter by Destination IP | ip.dest == 10.10.50.1 |
| Filter by Source IP | ip.src == 10.10.50.1 |
| Filter by IP range | ip.addr >= 10.10.50.1 and ip.addr <= 10.10.50.100 |
| Filter by Multiple Ips | ip.addr == 10.10.50.1 and ip.addr == 10.10.50.100 |
| Filter out/ Exclude IP address | !(ip.addr == 10.10.50.1) |
| Filter IP subnet | ip.addr == 10.10.50.1/24 |
| Filter by multiple specified IP subnets | ip.addr == 10.10.50.1/24 and ip.addr == 10.10.51.1/24 |
