You can change the key bindings in Merge the same as in Text, though unlike Text there isn’t a menu entry that opens the requisite files for you automatically. In Text that’s implemented as a plugin and Merge currently doesn’t support plugins. So you have to do this sort of thing manually at the moment.
You can use Preferences > Browse Packages
from the menu to open up the location where Merge stores its unpacked packages, and inside of there is your User
package.
The key binding you want is:
{ "keys": ["alt+space"], "command": "show_command_palette" },
To put it in place, you need to create an appropriate key binding file, which would be something like Default (Windows).sublime-keymap
(and/or Linux
or OSX
in place of Windows, depending on your situation).
You can also customize other bindings as well; for example I have this one in place so that switching repositories in Merge works the same as switching projects in Text:
// Mimic quick switch project in Sublime.
{ "keys": ["ctrl+alt+p"], "command": "quick_switch_repository" },
To find the default bindings you need to look in the Packages
folder that’s inside of the folder where you installed Merge; there is a Default.sublime-package
and a Default - Merge.sublime-package
present in there. Copy them out to somewhere else and rename them to .zip
files instead, and you can look inside to see what the default bindings, menus and so on contain.
