Keyboard Shortcuts¶

General¶

Key	Action
`?`	Show / hide the in-app key reference
`q` / `Esc`	Step back one level: clear the text selection, then leave zoom, then clear the filter, then quit
`Ctrl+C`	Quit immediately
`c`	Clear all exchanges
`s`	Toggle sort: capture order / slowest first
`p`	Pause / resume capture
`Tab`	Switch focus between panes

Copy and export¶

Key	Action
`y`	Copy the whole exchange (request and response)
`1` / `2`	Copy the request / the response
`3`	Copy the request as a `curl` command
`e`	Export the listed (filtered) exchanges to `tylomon-<timestamp>.har` in the current directory

Dragging in the detail pane copies the selected text, see Mouse. Copy confirmations replace the key hints in the status bar for a few seconds.

Key	Action (List pane focused)	Action (Detail pane focused)
`j` / `Down`	Select next exchange	Scroll down
`k` / `Up`	Select previous exchange	Scroll up
`g`	Jump to first exchange	Scroll to top
`G`	Jump to last exchange and follow new ones	Scroll to bottom
`PgDn`	Page down (10 items)	Scroll down (10 lines)
`PgUp`	Page up (10 items)	Scroll up (10 lines)

Mouse¶

Action	Effect
Click an exchange	Select it and focus the list
Double-click an exchange	Select it and focus the detail pane
Click the detail pane	Focus it
Drag inside the detail text	Select text; it is copied to the clipboard when you release the button
Double-click a word in the detail text	Select and copy that word (paths, header values, JSON strings)
Drag above or below the detail text	Keep selecting while the content scrolls
Wheel over the detail pane	Scroll it
Wheel over the list	Move the selection
Click an edge in the service map	Select it
Double-click an edge	Show that edge's requests in the list
Wheel over the service map	Move the selection
Wheel over the help	Scroll it
Click outside the help	Close it

Selection stays inside the scrollable part of the detail pane (headers and bodies), never the list or borders. Lines that were only wrapped to fit the pane are copied as one line, without the wrap indent. Esc, a click elsewhere, or selecting another exchange clears the highlight. The pinned summary at the top is not selectable; use 1, 2, 3 or y to copy whole messages.

Clicks are ignored while the filter prompt is open. Dragging is ignored while a pane is zoomed.

Layout¶

Key / action	Effect
`z`	Zoom the focused pane to full screen. `Tab` switches to the other pane, still full screen; `q` or `Esc` returns to the split
`<` / `>` (or `,` / `.`)	Make the list pane narrower / wider
`=`	Reset the split to the default
Drag the border between the panes	Resize them continuously
Double-click the border	Reset the split

Each pane keeps at least 20 columns. A zoomed list is useful for long paths and the src→dst column; a zoomed detail pane gives wide hex dumps (16 bytes per row) and fewer wrapped lines. The split is not saved between runs.

Follow¶

Key	Action
`f`	Toggle follow: the newest exchange stays selected as traffic arrives. Moving up or `g` turns it off; `G` turns it on.

The selection tracks the exchange itself, not its row, so it stays put when new exchanges arrive, the sort changes or a filter still lists it.

Detail pane¶

The top of the pane stays pinned while the content scrolls: request line (method and path), a coloured status badge with response time and body sizes, the source and destination with the capture time, then request headers, request body, response headers and response body. A position indicator and scrollbar appear when the content is longer than the pane.

JSON bodies are pretty-printed with coloured keys, strings, numbers and keywords.
Bodies that are not valid UTF-8 text are shown as a hex dump with an ASCII column (first 8 KB).
Text bodies over 256 KB are cut off with a notice; copy with y, 1 or 2 for the full body.
Requests that never received a response are marked NO RESPONSE.

Service map¶

Key	Action
`m`	Toggle the service map (from the list) / return to the list
`j` / `k`	Select next / previous edge
`g` / `G`	First / last edge
`Enter`	Return to the list, filtered to the selected edge (`src:… dst:…`)
`q` / `Esc`	Return to the list

The map groups the filtered exchanges by source, destination and destination port, busiest first. Columns: request count, 4xx responses, Failed (5xx responses plus requests that never got a response), failure percentage, and p50/p95 response time (nearest-rank, answered requests only). Active filters apply, so / with >500ms shows only the slow traffic per edge. p, /, e and c work as in the list.

Key	Action
`/`	Open search filter
`Enter`	Apply filter (in filter mode)
`Esc`	Cancel filter input / clear active filter
`Backspace`	Delete last character (in filter mode)

Filters are case-insensitive. Separate terms with spaces; all terms must match.

Term	Matches
`word`	Method, path, status code, or source/destination name or IP
`src:api`, `dst:gateway`	Source / destination container name or IP (substring)
`method:post`, `path:/users`	Method / path (substring). For PostgreSQL the method is the statement verb and the path is the SQL
`proto:http`, `proto:pg`, `proto:grpc`	Protocol (`postgres`, `postgresql` and `sql` also work)
`status:404`, `status:5xx`, `status:>=400`	Exact status, status class, or comparison (`<`, `<=`, `>`, `>=`)
`>500ms`, `<2s`, `>=1.5s`	Response time
`!term`, `-term`	Negates any term above

Examples:

status:5xx dst:api         server errors from the api container
>500ms -path:/health       slow requests, ignoring health checks
method:post !status:2xx    failed POSTs
proto:pg >100ms            slow SQL queries
proto:pg status:5xx        failed SQL statements
proto:grpc status:5xx      gRPC calls that did not return OK

Exchanges still waiting for a response never match status: or duration terms.

Response time colours¶

Response times are shown dimmed, yellow from 300 ms and red from 1 s.
