Lazy Select earns a place in the Superhive library for a focused idea: one selection mode that adapts to whatever you hover over, with bookmarks for repeated selections.
Lazy Select works inside Blender's Edit Mode to remove the need to switch between vertex, edge and face selection modes. After activating with Alt+Q from Vertex Select Mode, the tool automatically detects the element you're hovering over, so you no longer press 1, 2 or 3 to change modes. Blue highlighting shows what you'll select before you click.
Selection is handled through familiar interactions: left-click for a single element, double-click for edge loops, Alt+Click for face loops, and Shift+Click for multiple elements. Parallel loop selection reduces the last-edge case from at least four clicks in default Blender to two. The tool also supports moving and extending selections, and press ESC to deactivate. When the tool is off, all Blender shortcuts work normally.
Selection Bookmarks let you save and restore selections. From the N-Panel under Lazy Select, you can select faces, edges or vertices, bookmark the selection, restore it via the play icon, and rename or delete bookmarks. Version 1.1 adds ESC to deactivate and parallel loop selection. The add-on has not been tested on macOS, and the developer welcomes volunteers to help test it.
Updated! Lazy Select is best for blender modelers who work with repeated selections and want to select vertices, edges and faces without changing modes.
Updated! Lazy Select is completely free to download and use.
Lazy Select is listed for Blender versions 4.4 through 5.0. If you run a build within that range, the add-on is intended to work with your version. Note that the tool has not been tested on macOS, and the developer has asked for volunteers to help test it on that platform. If you're on macOS, factor that in before relying on it, and check the developer's page for the latest compatibility notes and any updates to the supported version range.
Lazy Select follows a set sequence: enter Edit Mode, go to Vertex Select Mode, then press Alt+Q to activate. Once active, hover to see the blue highlight and left-click to select. Double-click selects edge loops, Alt+Click selects face loops, and Shift+Click selects multiple elements. Press ESC to deactivate the tool. Selection Bookmarks are accessed from the N-Panel under Lazy Select, where you can bookmark a selection, restore it with the play icon, and rename or delete bookmarks.
Lazy Select is listed as free here, and it is released under the GPL license. The developer's page also shows optional supporter tiers if you want to contribute. For the current licensing terms, download options and any supporter details, check the developer's page directly. Because terms can change over time, confirming there before you download ensures you have the most accurate and up-to-date information about how the add-on is distributed.
Lazy Select V1.1 introduces ESC to deactivate the tool, replacing the previous need to right-click to exit. It also adds parallel loop selection, which reduces selecting the last edges from at least four clicks in default Blender down to two clicks. A note in this version flags that the add-on has not been tested on macOS, with the developer inviting volunteers to help test it. A demo video is available if you want to see the tool before installing.
