Snippet Authoring Strategy & Trigger Conventions

A well-structured snippet library prevents accidental expansions and ensures intuitive recall under fast typing conditions.

The Three Proven Trigger Prefix Conventions

Semicolon Prefix (;addr)

The pinky finger rests naturally on the semicolon on QWERTY keyboards, making it the fastest single-stroke delimiter.

Colon Prefix (:sig)

Standardized by Espanso and Slack emoji shortcodes. Highly memorable and immune to accidental prose matches.

Double-Letter Prefix (qqemail)

Doubling an infrequent letter (e.g. qq, jj, xx) eliminates the need to reach for punctuation characters altogether.

Dynamic Placeholder Reference

Dynamic Tag	Sample Output	Execution Behavior
`{{date}}` / `{{date:YYYY-MM-DD}}`	`2026-08-27`	Injects the current local system date at the exact moment of trigger firing.
`{{time}}` / `{{time:HH:mm}}`	`14:35`	Injects current 24-hour or 12-hour local system clock time.
`{{clipboard}}`	`https://example.com/item/42`	Reads current operating system clipboard contents into the expanded template.
`{{cursor}}` / $\|$	Cursor positioned here	Places the active typing caret at this exact spot inside the inserted text.
