+==============================================================================
+15. Language Server Protocol			*language-server-protocol*
+
+The language server protocol specification is available at:
+
+    https://microsoft.github.io/language-server-protocol/specification
+
+Each LSP protocol message starts with a simple HTTP header followed by the
+payload encoded in JSON-RPC format.  This is described in:
+
+    https://www.jsonrpc.org/specification
+
+To encode and send a LSP request/notification message in a Vim |Dict| into a
+LSP JSON-RPC message and to receive and decode a LSP JSON-RPC
+response/notification message into a Vim |Dict|, connect to the LSP server
+with the |channel-mode| set to "lsp".
+
+For messages received on a channel with |channel-mode| set to "lsp", Vim will
+process the HTTP header and decode the JSON-RPC payload into a Vim |Dict| type
+and call the |channel-callback| function or the specified
+|channel-onetime-callback| function.  When sending messages on a channel using
+the |ch_evalexpr()| or |ch_sendexpr()| functions, Vim will add the HTTP header
+and encode the Vim expression into JSON.  Refer to |json_encode()| and
+|json_decode()| for more information about how Vim encodes and decodes the
+builtin types into JSON.
+
+To open a channel using the 'lsp' mode, set the 'mode' item in the |ch_open()|
+{options} argument to 'lsp'.  Example: >
+
+    let ch = ch_open(..., #{mode: 'lsp'})
+
+To open a channel using the 'lsp' mode with a job, set the 'in_mode' and
+'out_mode' items in the |job_start()| {options} argument to 'lsp'. Example: >
+
+    let cmd = ['clangd', '--background-index', '--clang-tidy']
+    let opts = {}
+    let opts.in_mode = 'lsp'
+    let opts.out_mode = 'lsp'
+    let opts.err_mode = 'nl'
+    let opts.out_cb = function('LspOutCallback')
+    let opts.err_cb = function('LspErrCallback')
+    let opts.exit_cb = function('LspExitCallback')
+    let job = job_start(cmd, opts)
+
+Note that if a job outputs LSP messages on stdout and non-LSP messages on
+stderr, then the channel-callback function should handle both the message
+formats appropriately or you should use a separate callback function for
+"out_cb" and "err_cb" to handle them as shown above.
+
+To synchronously send a JSON-RPC request to the server, use the
+|ch_evalexpr()| function. This function will wait and return the decoded
+response message from the server. You can use either the |channel-timeout| or
+the 'timeout' field in the {options} argument to control the response wait
+time.  If the request times out, then an empty |Dict| is returned.  Example: >
+
+    let req = {}
+    let req.method = 'textDocument/definition'
+    let req.params = {}
+    let req.params.textDocument = #{uri: 'a.c'}
+    let req.params.position = #{line: 10, character: 3}
+    let defs = ch_evalexpr(ch, req, #{timeout: 100})
+    if defs->empty()
+        ... <handle failure>
+    endif
+
+Note that in the request message the 'id' field should not be specified. If it
+is specified, then Vim will overwrite the value with an internally generated
+identifier.  Vim currently supports only a number type for the 'id' field.
+The callback function will be invoked for both a successful and a failed RPC
+request.
+
+To send a JSON-RPC request to the server and asynchronously process the
+response, use the |ch_sendexpr()| function and supply a callback function.  If
+the "id" field is present in the request message, then Vim will overwrite it
+with an internally generated number.  This function returns a Dict with the
+identifier used for the message.  This can be used to send cancellation
+request to the LSP server (if needed).  Example: >
+
+    let req = {}
+    let req.method = 'textDocument/hover'
+    let req.id = 200
+    let req.params = {}
+    let req.params.textDocument = #{uri: 'a.c'}
+    let req.params.position = #{line: 10, character: 3}
+    let resp = ch_sendexpr(ch, req, #{callback: 'HoverFunc'})
+
+To cancel an outstanding asynchronous LSP request sent to the server using the
+|ch_sendexpr()| function, send a cancelation message to the server using the
+|ch_sendexpr()| function with the ID returned by the |ch_sendexpr()| function
+for the request.  Example: >
+
+    " send a completion request
+    let req = {}
+    let req.method = 'textDocument/completion'
+    let req.params = {}
+    let req.params.textDocument = #{uri: 'a.c'}
+    let req.params.position = #{line: 10, character: 3}
+    let reqstatus = ch_sendexpr(ch, req, #{callback: 'LspComplete'})
+    " send a cancellation notification
+    let notif = {}
+    let notif.method = '$/cancelRequest'
+    let notif.id = reqstatus.id
+    call ch_sendexpr(ch, notif)
+
+To send a JSON-RPC notification message to the server, use the |ch_sendexpr()|
+function. As the server will not send a response message to the notification,
+don't specify the "callback" item.  Example: >
+
+    call ch_sendexpr(ch, #{method: 'initialized'})
+
+To respond to a JSON-RPC request message from the server, use the
+|ch_sendexpr()| function.  In the response message, copy the 'id' field value
+from the server request message. Example: >
+
+    let resp = {}
+    let resp.id = req.id
+    let resp.result = 1
+    call ch_sendexpr(ch, resp)
+
+The JSON-RPC notification messages from the server are delivered through the
+|channel-callback| function.
+
+Depending on the use case, you can use the ch_evalexpr(), ch_sendexpr() and
+ch_sendraw() functions on the same channel.
+
+A LSP request message has the following format (expressed as a Vim Dict).  The
+"params" field is optional: >
+
+    {
+	"jsonrpc": "2.0",
+	"id": <number>,
+	"method": <string>,
+	"params": <list|dict>
+    }
+
+A LSP reponse message has the following format (expressed as a Vim Dict).  The

 <ScrollWheelUp> key press is generated causing the window to scroll upwards
 (while the text is actually moving downwards).  The default action for these
 keys are:
-    <ScrollWheelUp>	    scroll three lines up	*<ScrollWheelUp>*
