include/imgui/imgui_widgets.cpp:832–840

Small buttons fits within text without additional vertical spacing.

// Small buttons fits within text without additional vertical spacing.
bool ImGui::SmallButton(const char* label)
{
    ImGuiContext& g = *GImGui;
    float backup_padding_y = g.Style.FramePadding.y;
    g.Style.FramePadding.y = 0.0f;
    bool pressed = ButtonEx(label, ImVec2(0, 0), ImGuiButtonFlags_AlignTextBaseLine);
    g.Style.FramePadding.y = backup_padding_y;
    return pressed;
}

// Tip: use ImGui::PushID()/PopID() to push indices or pointers in the ID stack.
// Then you can keep 'str_id' empty or the same for all your buttons (instead of creating a string based on a non-string id)
