When to use OMAP or IMAP in Vim?

vmap maps keys in visual mode only. So, use imap if you want to set a mapping that works in Vim’s insert mode, cmap for mappings to work in command (last line) mode, omap to map keys to function after an operator has been used in normal mode, and so on.

Can a route map be used to deny redistribution?

Fortunately, route-maps that are applied to redistribution behave the same way as ACLs: if the route does not match any clause in a route-map then the route redistribution is denied, as if the route-map contained deny statement at the end. The dynamic protocol redistribute configuration command allows you to apply either an ACL or a route-map.

What’s the default timeout for mapping keys in Vim?

When the ‘timeout’ option is set (which is the default), then Vim waits for the number of milliseconds specified in the ‘timeoutlen’ option for a mapped key sequence to complete. The default setting for ‘timeoutlen’ is one second. If the ‘timeout’ option is reset, then Vim will not timeout for mapped key sequences.

Can you create a map for Ctrl-J in Vim?

When the map is invoked, Vim replaces the two Ctrl-V characters with a single Ctrl-V character. The Ctrl-J character represents the linefeed and is internally used by Vim to represent the Nul character. You cannot create a map for Ctrl-J by using the following command:
